At almost 65yo prior to my bilateral Orchiectomy for Prostate Cancer 4 years ago this month I had the mandatory pre-OP EKG and the reading was 32bpm. Nurse questioned it and I mentioned about just missing my 2015 IM70.3FL race due to the TRUS biopsy and my training for it and other events resulted in the lowered HR. I am often questioned about the low resting rate at first time doctor visits and prior to surgeries and simply reply "endurance athlete effect." While in ER following my 4/16/2011 bicycle crash at mile 72.5 of a 100 miler that resulted in a minor broken neck the HR monitor kept on going off also due to low HR. They re-adjusted and things were fine. My multiple ECHO results have shown a large athletic heart with some minor leaky valves but nothing really wrong.
