IWatch ECG app use with ICD

Does anyone know if using the ECG app on your IWatch will interfere with the ICD or pacemaker? I don't see a lot of information on this subject. Thanks!


Interefere with your pacemaker?

No, it won't hurt your pacemaker or interfere with it's operation.  However, its utility will be limited.  They're not programmed or approved to "see around" pacing spikes.  Any automatic functions, like Afib detection, won't likely won't work but the EGK itself might be useful to the trained eye.  If your EP will accept it, he can read it. He can also use your PM directly (and use tools designed for the job) and would probably rather do that. 

You can learn to read your EKG yourself. Depending on what you're looking for, it might be easy to learn how to spot it.  OTOH, some things just can't be seen on a one-lead EKG (e.g. flutter).

If you're looking for it as a justification for an iWatch, it won't be useful enough. A six-lead Kardia would be a better, cheaper, alternative but even that will be limited (no automatic functions).  If you have an iWatch, sure, use it for your own edification.  To buy one to read EKGs, no.  Just my opinion.

Thank you for your reply. I have a two lead ICD that should only go into action if needed, so no pacing (at this time). Just wanted to make sure it wouldn't affect the ICD. Thanks again!

Should Be Fine

I have had an Apple Watch for years and find it very useful ever since getting the mechanical valve and eventually my pacemaker. I can generally tell what my "normal" rhythm is , so it helps if I'm feeling off and want to check on things. I was able to finally describe and prove bouts of PVCs that I was having, because my Watch recorded them and my cardiologist finally saw them when I shared the results. 

I also like it to keep an eye on the heart beat as I've been experiencing SVTs and it's comforting having something show what I am experiencing. Although sometimes I find myself obsessing over it and staring at it far too much -- try not to let that happen. 

Lastly, if you get a cellular version you can turn on the fall assist option, which alerts 911 if you suddenly fall and don't respond -- for me, a peace of mind that I'd rather have and not need or use than not have and need. 

take care

I finished 29th in London in 2 hours 20 minutes 30 seconds which is my fastest with or without a device so clearly it didn’t slow me down ! I had no problems apart from some slight chaffing on my scar - more Vaseline next time.
