Endurance athletes & HCM
I had an SCA 16 years ago. I was out for a run. It was dramatic. I've got an implanted ICD. About 5 years ago I decided to make a change. The "box" hadn't gone off in 16 years and I had developed a weight problem from lack of exercise (and sub-par diet). I started back up on the bicycle. I've been riding about 4,000 to 5,000 miles/year. I tend to avoid most of the high intensity training but I live in Seattle. It's not flat. I climb lots of hills. In the first quarter I had some problems with AFIB (apparently my heart is uniquely skilled at arrhythmia.) 3 ablations & a couple cardioversions later . . . I've logged LOTS of low/slow miles over the last 4 months. But my performance isnt what it was a year ago. I met with my EP cardiologist today. His theory is that as I get older (I'm 53), my HCM is causing my heart to "stiffen" and not "refill" with blood as effectively after pushing the blood out. I get that I'm not one of the fast kids nor am I going to train myself into position to be part of that group. And, I'm interested if there are others in the same camp athletically as me. I'm interested in your experience. I'm not competitive so that's not on my goal list . . . but I do group rides & a fair amount of bike touring.
