Thanks "scottbeammeup".
We're the same but different - like most things PC.
I've had several, maybe dozens, of A-fib episodes. Some before Lupron and some during. All but two were totally invisible to me; very strange. I've had a "loop monitor" for almost 2-years now and it picked up many at all hours of day/night that I never felt. But then one, when I was stressed again, literally put me on the ground one day. Thought I was gonna die. So Cardio Doc (who is super and specializes in Electrocardiology) then did an ablation (common treatment for A-fib) and all has been well since. But I still and will carry Metropolol with me. Thanks for sharing and hope others with PC don't add this to their lists. Enough already!
