I am a very active 46 year old that was experienceing some chest pains and took a stress test. Afterwards, the cardiologists stated that it was the best he had seen in two years. I also referee high school basketball games and had donme around 100 this year as well. I do at times though experience some unexplainedc fatigue. The family doctor stated that there was a question about my left ventricle. My heart rate got up to 162 after 21 minutes. After 90 seconds it was down to 108; I thought, no problem. Anyweay, had an echo and they stated that my ejection fraction was down to 50%. What I didn;t know was that in 03 it was 40%. He has ordeered a gold standard test this weekend. I like to lkift weigfhts; hard and train hard. Just finished backpacking across ITaly in the 93 degree weather. Myu question is , should I be worried? Should i stop training so hard? My gut tell sme no but I guess my doctors are being thoutough. I find it odd that no one told me anything in 03 about my EF rate. The cardiologist told me that it seems as if the rate is going in a good direction.
