Hey OP - I’m an internal medicine physician. Not medical advice but I think a good priority for any watch you get would be one that has automatic fall detection/alert. If you do flip into VT again and your ICD goes off you may be in a position where you are unable to call for help.
I believe most newer gen Apple Watches and Garmins have this feature. Just a thought!
That’s very smart. And kudos to you for getting back to what you love. I can’t imagine going through what you’ve gone through - wish you all the best!
