Myocardial Fibrosis in Athletes: Risk Marker or Physiological Adaptation?

I got a bunch of workups because I fainted when exercising on a hot day when I'd eaten a bit too much and was a little infatuated with the instructor (I was the only student.) I got the plain echo and a stress echo and was told I had athlete's heart which they are not so sure if it is good or bad. I also wore a Holter monitor for 30 days and literally at the last 5 minutes of the period I had two bad heart beats so now I have A-Fib on my chart and my doc says the athlete's heart can make it worse so since then I'm only supposed to do an hour a day of cardio.

When all this was going on I had manifested an "evil twin" whose harebraned scheme had just blown up right at the time I had those two bad heartbeats and I can't believe the emotional distress I'd caused myself hadn't had anything to do it. I have one of those Kardia cards and haven't seen it happen again.
