I'm seriously bummed. I'm 56 yrs. old, a former USCF cat 2 rider. I have developed atrial fibrillation (an abnormal, arrythmic heart beat). The cause of this is unknown, but when it occurs, the heart functions at about 70% of normal capacity. It amounts to an electrical disturbance within the heart. There is (according to my Doc) no serious threat with this & he said I could ride all I want. Trouble is, it seems to be exercised induced. Last time I rode , the firat 10 mi., I did fine, felt ok. Then went into arrythmia & rode homw averaging 15 mph.
Anybody out there (masters, vets, or other) got any suggestions, knowledge, etc?? Any responses would be most welcome.
