@lakehappy Oh, yes, I too, am worried about getting zapped by Buddy, my ICD! It has not happened, that's not to say it never will. I think that those who have are grateful an ICD was there at their time of need. You are right on top of everything with a referral to an electrophysiologist and that you have a "great cardio team with expertise with HOCM." There are many excellent providers, mine included, who are not associated with a COE, but trained at a place that is now a COE. I hope your electro doctor appointment is in the near future - please reach out as you move along in your journey.
