Just did a two week holter test for palpations (found it was caffeine induced) my primary said nothing concerned him although I had a high heart rate 1% of the time. Over 100. He said it was high normal not abnormal. The over 100 corisponded with walking on my apple watch. I've tested a few things. 4 MPH walk for 15 min yielded a average heart rate of 118. 50 BPM cardiac recovery after 3 mins. Resting heart rate is 49 to 52. What concerns me is normal walking around my heart rate is 105 to 110. That seems high to me. Im 6'1 210 lbs. LDL was 59, HDL 75, trygliseride 25. Should I find a cardiologist?
