Implantable Cardioverter Defribrillator Exercise

The prospect of having an implantable cardioverter defibrillator (ICD) installed can be daunting news.  Nobody wants a slab of metal inserted into their chest, but once you educate yourself on ICDs and the conditions they treat, you will find that you can live a relatively normal life and do most things you did before having it installed – only with our the worry of an arrhythmia stopping you dead in your tracks.

Your heart beats in a controlled rhythmic manner in order to efficiently deliver blood—and the oxygen and nutrients it carries—to different parts of your body. Any disturbance in the heart’s electrical conduction system (arrhythmia) may compromise its ability to pump blood.

While some heart rhythm abnormalities like atrial fibrillation can be managed with anti-arrhythmic medications, in other cases, comparably more dangerous ventricular arrhythmias—irregularities propagated in the lower chambers of the heart—may require you to be fitted with an implantable cardioverter defibrillator.

What is an implantable cardioverter defibrillator?

An implantable cardioverter defibrillator is a small, thin, battery-powered device implanted just under the skin in the chest region (see image below) and is designed to deliver a shock to restore normal cardiac rhythm in those at risk for sudden cardiac death due to malignant arrhythmias like ventricular fibrillation or tachycardia.

These conduction disturbances may be the result of a heart attack, cardiomyopathy (diseased heart muscle), or a congenital defect, all of which can interrupt the normal electrical conduction pathways in the heart. While the implantable cardioverter defibrillator may be an inconvenience at first, many of the ICD patients I’ve worked with in cardiac rehabilitation adjusted their lifestyles and went on to live quite enjoyable and productive lives.

If you learn more easily by watching videos, here is a very short 3D animated clip about ICDs which explains the procedure in very simple terms.

Can I exercise safely with an implantable cardioverter defibrillator?

When I teach fitness professionals about training clients with heart problems, invariably the question arises, “how do I exercise someone with an implantable cardioverter defibrillator?” My short answer is, not too differently from anyone else, except for several precautions (to be addressed below).

As a clinical exercise physiologist, I’m generally less worried about someone WITH an implantable cardioverter defibrillator because this tells me they’ve been diagnosed, treated, and are now under the care of a cardiologist.

It’s the person with malignant arrhythmias WITHOUT an ICD that keeps me awake at night! As stated above, your implanted cardioverter defibrillator is designed to “zap” you back to normal rhythm in the event your heart starts racing or beating erratically.

Exercise also causes your heart rate to increase, but this is a normal and expected response. So how does your implantable cardioverter defibrillator tell the difference between a potentially dangerous heart rate or rhythm versus normal exercise-induced increases in heart rate?

Generally speaking, your  implantable cardioverter defibrillator will be programmed by your electrophysiologist to detect both abnormal heart rates and rhythms which are likely to be outside the range of what you’d accomplish with most daily activities or moderate exercise (which will minimize unnecessary or inappropriate shocks).

Your medical management team should give you safe exercise heart rate limits for your implantable cardioverter defibrillator settings. Your doctor may wish to carry out an exercise stress test to simulate your usual exercise intensity and “troubleshoot” any problems before they happen.

Tips for safe exercise with an ICD

The following tips will help you safely return to (or begin) an exercise regimen, but please understand these are general recommendations and are not a substitute for your doctor’s advice.

  • First and foremost, before you start or return to your exercise regimen, it is absolutely imperative that you are medically stable, your implantable cardioverter defibrillator has been fitted and programmed, you’ve been educated on your specific condition and understand your ICD limits, and you are well-managed (i.e., medications like beta-blockers which preclude your heart rate from climbing too high).
  • Wear an ID bracelet and have your  implantable cardioverter defibrillator card with you at all times. It will inform those around you of your condition if you are unable to speak for yourself.
  • Exercise with a friend or family member who is familiar with your condition and knows what to do in the event of an emergency.
  • The ICD can be affected by magnetic or electrical fields. In the gym setting, bioelectrical impedance analysis (BIA) is a technology used for assessing body composition (percent fat, muscle, water). You should avoid this and opt for something simpler such as the sum of skinfolds. Heart rate monitors are unlikely to cause any problems in the gym setting.
  • If you’re an athlete with a congenital heart defect and are accustomed to training and competing at high intensities, you should discuss your specific situation with your medical management team. They can adjust your  implantable cardioverter defibrillator settings to recognize the difference between a normal increase in heart rate from exercise and that associated with an abnormal heart rate or rhythm. Clearly an ICD is not the most convenient gadget for playing sports, but it will significantly minimize the risk of sudden cardiac death.

Exercise prescription for implantable cardioverter defibrillator

The four fundamental components of an exercise prescription are easily remembered by the FITT acronym: Frequency, Intensity, Time (duration), and Type of exercise. So a basic exercise prescription for a person with an implanted cardioverter defibrillator might entail the following:

Frequency

No matter if you’re new to exercise or are already a regular exerciser, after your  implantable cardioverter defibrillator placement (and perhaps recovery from a heart attack or other health concern) you may feel a bit tired and lethargic. If so, congratulations, you’re human and completely normal.

I suggest easing into exercise with a three-day per week regimen at first, and slowly add on days as your body adapts and you feel stronger. In this case, I am referring to structured conscientious exercise with purpose. However, with regards to background activities,

I also encourage you to do daily incidental movement, such as walking to the corner shop for a liter of milk, down to the post office, etc. There is a lot of new evidence surfacing in the medical literature which shows this background activity plays an important role in both weight loss and weight management.

Intensity

Intensity refers to how hard you’re exercising. Once you get your ICD implanted, you should ease into your routine. A sharp spike in heart rate could potentially set off your ICD. Therefore, you should include a low-level 5 to 10 minute warm-up and cool-down phase for aerobic exercise (i.e., walking, cycling) to allow for a slow and steady increase in heart rate.

After that, work up to a low to moderate intensity. A good pragmatic range is around 60 to 75% of your age-predicted max heart rate, but you can adjust this up or down depending on your relative fitness level and if it’s appropriate based on your physician’s advice.

In the exercise business, a best “guestimate” of your maximum heart rate is 220 minus your age. From this number, you then calculate a training heart rate range.

So if you’re 40 years old, then it’s 220 – 40 = 180 (theoretical max heart rate).

Next, 180 x 60% = 108 beats per minute and 180 x 75% = 135 beats per minute.

Therefore you would want to exercise in the range of 108 to 135 beats per minute.

If you have a hard time finding your pulse, get yourself a heart rate monitor or a Fitbit (which also tracks your non-exercise movement habits). Click on each image to check out features and thousands of Amazon user reviews.

I have worked with numerous ICD patients who wore them and there is no concern of this interfering with the device. Check with your doctor if you have any questions.

The effects of beta-blocker medications 

If you are taking beta-blocker medication, then your heart rate will remain blunted and will not fit neat and clean into the above heart rate calculation.

In this case, we like to use what is known as the Rating of Perceived Exertion (RPE). There are two RPE scales out there, so to eliminate confusion, I will use the 0 to 10 scale. In brief, 0 is sitting down at rest doing nothing and a 10 is an all-out effort to exhaustion.

Try to exercise at a “moderate” level, somewhere in the range of 4 to 6, and adjust based upon your body’s response. Also take note of your heart rate when you’re at a moderate workload. Though you’re on beta-blockers, this will reflect your individual response to exercise and can help serve as a guide.

If your dosage changes, then you may need to redo the above “experiment” to determine your new exercising heart rate. In my professional experience, people on beta-blocker medications will see a heart rate increase of approximately 20 to maybe 50 beats above rest, but again, this is variable and will likely reflect the dosage.

Time (Duration)

The length of your individual exercise sessions will vary, but as with the other exercise prescription components, you may want to start off on the low end and progress to longer durations as your fitness levels improve. For example, begin with a leisurely 15 to 20 minute stroll and see how your body responds.

Then work up to 30 minutes the following week, then 40 the week after, and so on. Pay particular attention to the terrain. Start off walking on level ground and, once your fitness foundation is established, you may want to experiment with some small hills (low incline).

Again, speak with your doctor regarding your exercise intensity and ICD limits. This knowledge will help you to tailor your exercise prescription and reduce any fear or anxiety over getting shocked during exercise.

Type of Exercise

In this day and age, there are a million and one different exercises you can choose from, but the good news is that most fall into several broad categories. The main types of exercise are aerobic, resistance training, and flexibility training. For the purpose of this article, I will only discuss aerobic and resistance exercise. Heavy duty power lifting or anaerobic interval training may not be conducive for individuals with an ICD (unless cleared by your doctor to do so).

Aerobic training

Walking, bicycling, ellipitical trainer, rowing machine, dancing, aerobics classes, etc are all popular forms of aerobic exercise. Which is best? The one that you enjoy most and are most likely to remain consistent with!

Resistance training (weight lifting) with an ICD

There are mixed reviews on whether or not resistance training (weight lifting) is appropriate for people with an implanted cardioverter defibrillator.

Much of this confusion stems from the belief that heavy loads will place large demands on the heart which will cause an arrhythmia. While this is logical reasoning for very high intensity exercise, lifting lighter weights which do NOT leave you huffing and puffing and gasping for air are likely to be well-tolerated and can yield marked improvements in strength. This, in turn, will make daily living easier, thus reducing the likelihood that basic activities will not set off your ICD.

To begin, start off with a weight you can lift in the range of 10 to 15 repetitions. If new to weight lifting, begin with one set (i.e., one group of 10 to 15 repetitions) for the first couple of weeks and then graduate to two sets. It certainly won’t turn you into a muscled bodybuilder, but it is sufficient stimulus to confer appreciable improvements in strength. It is beyond the scope of this article to discuss every nuance of strength training, so I would suggest you hire a trainer for a few sessions to teach you proper form and technique.

Additional considerations for weight lifting exercise

  • Avoid lifting weights so heavy that they leave you grunting, groaning, and gasping for air. This may increase the intrathoracic pressure, forcing your heart to work harder, and consequently set the stage for a possible arrhythmia (and subsequent shock). Rule of thumb: EXHALE ON THE EXERTION. In other words, when the weight is being lifted against gravity, exhale to release that internal pressure.
  • Overhead lifting “may” put additional strain on your heart because it needs to pump blood “uphill” against gravity. You don’t necessarily need to avoid overhead movements, but may wish to use lower weights or do shoulder exercises like lateral raises or upright rows which minimize the overhead component. Bear in mind some overhead movements may aggravate the placement of your  implantable cardioverter defibrillator, particularly if it was recently implanted. Stock standard advice: speak with your doctor for specific guidelines.
  • Following on from above, in general, beware of exercises which might impact the physical placement of your  implantable cardioverter defibrillator. For example, watch out for any exercises which incorporate the shoulder girdle/chest area where there is the risk of a weight or bar bumping into your  implantable cardioverter defibrillator. If you’re doing flexibility exercises (i.e., yoga), be aware that certain movements could agitate the implantation site.

Prohibited exercises

  • Contact sports or other activities which could result in a jarring effect to your body are not recommended or should be judiciously engaged in ONLY with approval by your medical management team.
  • If you participate in water sports, you should do so with an exercise buddy in case you receive a shock, feel dizzy or lightheaded, or are disoriented and unable to exit the water by yourself. SCUBA diving is generally discouraged, perhaps due to the risk of drowning (if you are rendered unconscious). Then again, the best advice is to seek the advice of your medical management team who will be most familiar with your unique situation and best qualified to give you specific guidance.

Take home message

Appropriate exercise specific to ICD implantation can enhance your overall well-being and quality of life.  Regular training promotes healthy changes in the muscles and your collective cardiorespiratory (heart and lungs) system which, over time, makes your day to day living much easier.

Weight loss stemming from a healthy lifestyle reduces the overall load on the body and further reduces stress on your cardiovascular system.  As a result, your heart will not have to work as hard to meet metabolic demands, therefore reducing the load on the heart and consequently lessening the chances of an arrhythmia—and a shock from your  implantable cardioverter defibrillator. Now get out there and start living life again!

  1. If your Interventional Cardiac Defibrillator (ICD) is one of the over half of unnecessary ICDs cited by Duke University, you can manually manage the defibrillator between its two modes of being a pacemaker and a surge device. Exercises that expand the chest will alert the pacemaker to bring down the heart beat. You will probably feel cold and the muscles will become constrained. Exercises that extend or press on the left arm will make the defibrillator surge and increase blood flow to the muscles. To get mobility and motion, practice getting out of the pacemaker mode and surging the defibrillator. The Boston Scientific rep explained to me that because of being thinner than most Americans, my muscles were more sensitive. The Boston Scientific rep helped close the sale of the ICD at Newport Beach’s Hoag Hospital, just one month after their FDA recall. PacificHospitalists.com has oversight of Hoag Hospital and collaborated with United Health Care (UHC) insurance to get paid for the ICD that was non-evidenced and out-of-guidelines. Over ten tests of heart, neurology, blood pressure and diabetes were normal. Five providers billed for 27 chest X-rays over two weeks despite no heart problem. One provider billed for 10 chest X-rays, apparently feeling ten was the threshold for being unnecessary and fraudulent.

  2. The information on resistance training in the article was exactly what I was looking for. As a 17 year old with ARVD I have been left to discover my physical limitations on my own (my doctor is pretty hands-off when it comes to suggestions on exercise and my cardiac rehab program has limited knowledge of my condition and is more aerobic exercise focused). I have a good understanding of my aerobic abilities but did not know much about weight training. The suggestions in this article have a solid foundation of safety but also provide patients with a liberal guideline for exercise. Very encouraging to see a cardiologist with a balance between practicality, caution, and encouragement. Thanks!

    • Hi Sam,
      Thanks for your comment. I should correct you that I am a doctorate-level exercise physiologist and not a cardiologist. While the information provided in my article should not supercede the recommendations of your doctor, it is at least a general guideline to put you in the right direction. In many cases, signs and symptoms must be monitored before, during, and after exercise. Err on the side of caution and gradually work up in both intensity and duration. The more information you know about your condition, the safer you will be. Please feel free to post another comment if you have further questions. Thanks for the kind words and best wishes to you.

      Cheers
      Bill

  3. I like this article for the information but there is still one question I have been getting mixed answers about and I thought maybe someone could help.
    I’m 28 and 2 years ago I was diagnosed with Brugada Syndrome. I asked my cardiologist about lifting weights and he told me I am completely healthy for doing such a workout however I need to stay away from push ups, pull ups, and bench press because of the led wire going between my clavicle and top rib. he said I could fracture the wire.
    Then less than a year later another doctor told me is was nearly impossible to fracture the led wire because its so strong.
    So long story short, is it possible to fracture the led wire by performing exercises such as push ups, pull ups, and bench press?

  4. Thank you for posting this information. After years of wondering what was going on, trips to the ER, and misdiagnoses, I was finally diagnosed correctly with CPVT (at 43 y/o!) last January. I have an ICD now and am on a betablocker. I was a recreational marathoner before this happened (yes, I’m lucky to still be alive), and I have found adding resistance training invaluable to my recovery. I have worked my way back up to a half-marathon and am training for a November marathon, however I am SO MUCH SLOWER (as in 3 minutes a mile slower) than I was before the ICD and beta blocker. I use PLE as my guide, and I don’t see any increase in my speed (or decrease in PLE) even with increased, focused training. Is this what you’ve seen?

    • Hi Ashley,
      Sorry to hear you’re having a rough time with your training, but I am happy to see you’ve been correctly diagnosed and properly managed. Without working with you myself or being fully aware of your entire medical history, I could not reliably comment on your situation. I would advise you to find a university-qualified clinical exercise physiologist in your area who may be able to work with you and give you more specific guidance. Though you are right to note that beta blockers can sap your energy and leave you feeling lethargic. This might be something to discuss with your doctor regarding your dosage. Best wishes to you in your upcoming marathon!

  5. I am 66 and I have undergone CABG in 1996 and angioplasty in 2004. In April 2012 ICD implantation was done due to VT.My cardiologist has advised not to lift left hand above the shoulder but I presume this restriction was for first 6 weeks. I have now started 45 minutes brisk walk daily and I found myself quite energetic after exercise. But before ICD implantation I was regularly jogging for 45 minutes. Can I start it again?

    • Hi there, and thanks for your comment. While I cannot legally give specific advice to any one individual (there are many factors and I am not familiar with your entire medical history), there is evidence that the benefits of exercise with an ICD far outweigh a sedentary lifestyle with an ICD (in terms of weight management and other cardiac/metabolic risk factors). It is great to see that you’re performing 45 minutes of brisk walking which, in the grand scheme of things, may not be too far off of a slow jogging pace. The most prudent course of action at this point would be to ask your cardiologist if there are any concerns about your picking up the pace a bit. Provided the ICD is stable and you’re not doing too much aggressive upper body (arm/shoulder movement), your doctor may give you the green light to go a little faster. Hope this helps!

  6. Thanks for this very good information. I found it very interesting.I have an Icd which has gone off twice with physical activity.I have now learned to watch it and I’m thinking about a heart rate monitor I see my electrophysiologist soon and I will discuss this with him.

  7. Do you really want the negative in this sentence:
    “This, in turn, will make daily living easier, thus reducing the likelihood that basic activities will not set off your ICD.”

  8. Thanks for your Guidance. I had a defibrillator installed 5 weeks back (@ 43y/o).

    I am looking for some prescription exercise within Canada for people with ICDs. Is swimming a good exercise after full recovery from ICD surgery.?

    • Hello Parag, thank you for your comment. Once you are fully healed up, I suggest speaking to your cardiologist to ensure that the swimming motion won’t disrupt the ICD wires. The other thing to consider is if it discharges while you’re swimming. May be best to employ the buddy method to ensure you have someone looking out for you. Provided your doctor gives you the all clear, then you should probably be able to get back to your swimming. Write another comment after you’ve fully recovered and let us know how you’re going. Best of luck.

  9. National guidelines in many countries, as well as the scientific literature itself, continually advise professionals to avoid overhead resistance training “at first”. However, there is never a discussion about the time course for when it becomes safe or exactly what movements can be done once you’ve passed the “at first” threshold.

    There is a serious need to educate allied health professionals on WHY it becomes safer after a period of time. Also, coordination between exercise physiologists, trainers, and cardiologists to determine specific weight and movement thresholds for pacemaker/ICD patients would make environments like CR that much safer and effective.

    • I couldn’t agree more. It is definitely one of those nebulous areas of exercise physiology/cardiac rehab. In the absence of any firm guidelines, I think the safe and prudent path is to take it on a case by case basis and work closely with the cardiologists/cardiac nurses. I also think there is an element of trial and error in easing the patient into resistance training and evaluating their tolerance to it. Everyone is looking for cookie cutter “guidelines” but the operative word is “guidelines” and not the end-all-be-all this is the way it MUST be done. Thanks for your comment.

  10. My husband had defribullator surgery. March 13th. His primary cardiac physician thinks he needs at least two more weeks before he returns to work. The surgeon who implanted the device says he can return now. What concerns me is I think both doctors fail to understand that there are a battery of tests he must pass in order to be allowed to return to work. One involves fully extending his left arm and his right leg and then pulling his full body weight in a crawling position. He must do ten reps of this exercise. I feel that just a bit over a month after his surgery, especially after his doctor explained to me how critical it was that the leads not be pulled loose even one millimeter, or another surgery would be necessary, that someone is not understanding the gravity of the situation. My husband weighs 250 lbs. I think that is a bit too much weight for him to be pulling with his left hand in an overhead crawl at this point. Is the doctor just not getting it, or am I being overly protective?

    • Hi Theresa,
      You are justified in being concerned and you must always be a strong advocate for yourself and the people you love. How is your husband feeling now five weeks after the surgery? Has he tried any of the movements he’ll be required to do for the test? And if so, how did he fare? I think it’s wise to work closely with both the doctors and perhaps a clinical exercise physiologist from your hospital’s cardiac rehabilitation department (if they have one). I think getting a few heads on board will help allay your fears and help your husband transition back into his work role. Please let me know how you go with all this by leaving a follow up comment or send me an email. All the best.

  11. I am 31 years old and had an icd installed January 20 due to genetics that can cause sudden cardiac death and I have a heart block. I was an avid exerciser before and ran at least 5 days a week. I like to do half marathons and triathlons. After the icd, if I do anything that raises my heart rate above 150, it will just keep racing until my icd goes off. The first time it went off I was walking on the treadmill. The second time it went off I was trying to play basketball with friends and got shocked 3 times and the third time I was walking on the treadmill and got shocked 4 times. All times my heart rate got above 230. My question is what is a safe rate to get my heart rate up to because I am tired of getting shocked.

    • Hi Marsha,
      That is a great question and one which really doesn’t have a simple answer. The best answer to these types of questions is always the same: It depends. What might be a safe heart rate for you could be inappropriate for someone else, and vice versa. The best thing you can do in this case is speak to your cardiologist in depth and explain the situation. It is affecting your quality of life everytime you get a shock so clearly this should be investigated in order to find some sort of resolution (as soon as possible). I apologise for not being able to give you a finite answer, but my training is as a clinical exercise physiologist and not a cardiologist. You would, however, benefit by including an exercise physiologist as part of your treatment plan to work in partnership with your cardiologist. I think that will give you the best chance of getting all this under control. Stop back and leave another comment once you speak to your heart team. Kind regards, Bill

    • You shroud talk to your doctor. I had the same problem, genetic heart condition, avid exerciser. My cardiologist put me on betablockers so my heart doesn’t get out of control so easily. I’ve had the ICD for 18 months and have been exercising/running 5-6 times a week for 1 year. Is a lot harder to run on beta blockers but is much safer. No shocks so far!!

    • Marsha , hi my name is Chris and it sounds like we suffer from the same . Although they call it sudden cardiac arrest lol. Shoot Ive been shocked and have passed out with the ICD . I’m not looking forwrd to working out to get back in shape ,but we must forge on, not go quietly into that goodnight. We just have to be real carefull . I will be . Best of luck.

  12. Hi Bill,
    Just found this site and discussion and at last feel I have found someone able to understand and discuss the risks and methods of getting back into regular healthy exercise.

    I am a 56 year male. Last year was diagnosed with bradycardia and had pacemaker inserted, this go infected and had it moved to right hand side. 3 months later serious arythmia and defibrillated followed by cabg surgery. A couple of months later another arythymia and had icd implanted.

    Now I find myself struggling to develop and stamina. Up until 50’s was consistent exeriser including masters squash, weightlifting, skiing, golf and cycling. I have recently retired to look after my wife who has alzeihmers and am struggling to develop a regular training routine as I am lacking confidence in how hard to push myself. On walks of up to 7km at approx 6kmh my heart rate is 110-120 which is what I used to do when jogging. I would like to get back to spinning classes but scared on hiit training sending me into arythmia or shock.

    Any suggestions on appropriate training methodologies I could discuss with my electrocardioligist.

    • G’Day Wayne,
      Thanks for taking the time to write and share your story. Whilst I cannot give you any specific guidelines over the internet (since I’m unfamiliar with your detailed medical history), I would suggest discussing the following questions with your cardiologist:

      1) Was there any evidence of a heart attack (myocardial infarction) with/without heart muscle damage? I’m guessing not based on what you wrote, but it’s good to be thorough. I’ve had clients who were unaware they had a heart attack.

      2) What medications are you on and how will these impact your ability to tolerate higher intensities? Sometimes you can have all the desire to exercise in the world but medications can suck the wind out of your sails.

      3) Which arrhythmias did you experience? Were they atrial or ventricular arrhythmias? Usually the occasional premature ventricular contraction (PVC) is no big deal, but if you get long runs of PVCs where you become symptomatic, then you definitely need to see your doc.

      4) Discuss the settings on your pacemaker and ICD with your cardiologist regarding the triggers that will set them off. I would specifically discuss your desire to do higher intensity spinning classes again and what the risks are to your specific situation.

      All in all, I think it’s important to be very familiar with your particular health conditions and the limits settings on your pacemaker/ICD in order to know what you can do. Make sure it will not deliver a shock under normal circumstances even if you happen to reach a higher heart rate. I’ve worked with a lot of ICD patients in my cardiac rehab program and if they were properly managed they were able to live a reasonably normal life again.

      Hope this helps, Wayne. Take care and feel free to leave another comment after you’ve been to see your cardiologist.
      Kind regards,
      Bill

      • Dear Dr Sukala,
        => Would it be safe to be UNDER water/on the beach/in the low surf, just standing/sitting there, or some form of very limited activity, maybe yes/no, limited body surfing mindful of the leads?
        All very nice and easy; love the beach.
        Had ICD p/maker/defib implanted 6/52 ago post cardiac arrests/myopathy.
        On various cardiac medications now. Potential s/effects re sun/UV.
        Used to be regular/fit exerciser.
        Starting again. Walking.
        And:
        => Bicycle soon: have you heard if an e-bike is safe to use? Like a mixture of a bicycle with a scooter, based on Li battery driven electromagnetic motor? No driver’s licence required.

        Thank you for your reply in due course.

        • Hello Heinz,
          Thank you for your comment. I’m not quite clear on when you had your ICD implanted, but provided your surgery wasn’t too recent, then you should be ok to go in the water (once you have received clearance from your doctor). In the early post-op phase, you’d have to be very careful with the lead wires and overhead movements. Here is a quick link which may provide some extra helpful information: http://www.mayoclinic.org/tests-procedures/implantable-cardioverter-defibrillator/basics/results/prc-20015079

          Regarding the bicycle, I have heard of these types of bikes. Talk to your doctor about the heart rate limits set on your ICD to make sure it does not deliver you a shock when your heart rate rises normally with exercise. I think the newer models are better than the older models from years ago, but always best to check with your doc to be sure. Provided your heart rate is not going to climb too high, the bike probably wouldn’t be too much of a concern. But again, the final word should come from your doctor, as he/she is specific with your individual medical history and surgery.

          Hope this helps.
          Warm regards,
          Bill

  13. Hello

    In January 2014 I had a cardiac arrest whilst exercising on my bike at home and diagnosed with arrythmia, hence and ICD was fitted. The arrest was totally out of the blue and I have had no previous heart problems before or family history. I am now taking mg of bisoprolol beta blocker a day and feel absolutely fine and have regular check ups. There has been no problems since. I ave been told that any exercise that is over 130 beats per minute is not acceptable and only walking is good for me. This I find frustrating as I have put on 7 kilos over 2 years and as being used to exercise, I do feel very low about this at times. Also do I have to stay on beta blockers for ever?

    • Hi Julie,
      I can certainly understand your frustration. I would suggest speaking to your electrophysiologist (cardiologist) to discuss the ICD limits. Find out what the max heart rate is based on the ICD settings and if it is able to distinguish between elevated heart rates due to exercise (normal sinus tachycardia) compared to runs of ventricular tachycardia (the bad stuff). The beta-blocker is obviously meant to keep your heart rate down at levels low enough that the ICD doesn’t give you a shock.

      Having said all that, I can’t legally comment or give specific medical advice because obviously I’m not aware of your entire medical history and I’m not a cardiologist. I would suggest having another “heart to heart” (pun intended) with your cardiologist about these issues and see if you can work together (within the confines of your particular condition) to lower your beta-blocker dose, adjust your ICD limits, and allow you to get back doing exercise at a comparatively higher intensity that will help you lose weight.

      I hope this helps.

      Kind regards,
      Bill

  14. Hello,
    This is a nice article for guidance on exercise with an ICD. Very helpful!
    I received an ICD on February 4th 2012. 2 days before I suffered sudden cardiac death but was saved by several awesome people and an AED. I was 39 at the time. The root cause has never been identified even with genetic test. I went back to basketball and working out 4 or 5 days a week with no problems until Jan. 4 this year. My ICD shocked me 3 times (brutal) over an hour long period before I could get to the ER. Turns out the leads had fractured and a short caused the 3 shocks. My ICD was replaced. I backed off the amount and intensity of my exercise but still made it 3 days a week, no more basketball though. But, on August 20th this year, my ICD shocked me 5 more times. I was on a stair master at the gym. The Dr.’s and device techs all tell me it did what it was supposed to do on the first one (my heart beat was headed into a VFib again) but the other 4 were because a lead had moved so it was somehow misreading something. I find it hard to believe the lead misplacement didn’t help cause the initial rhythm/s but I’m not an EP so I have to go with what they say. I’m trying to put all that behind me and wanting to find some level of exercise that won’t increase my chance of another inappropriate shock. I was thinking yoga would be a good start with some bike for cardio. You mentioned yoga irritating the implant site…is that after recent surgeries are at anytime with an ICD? By irritation do you mean it’s an odd sensation or causes some swelling and pain?
    Thanks!

    • Hi CP,
      Thanks for your comment. I was just making a general comment regarding exercises which might affect the ICD, be it just after implantation or beyond. Anything that could affect the wires or bump the ICD needs to be carefully controlled (which applies to yoga as well). On that note, I think yoga is a good idea, but you’ll want to be careful. I’d suggest speaking to your cardiologist or the cardiologist’s practice nurse and discuss your concerns. Hope this helps. Cheers, Bill
