I usually have low blood pressure and a low pulse rate. During exercise I struggle to get my pulse over 105. Lately my pulse takes off when I am at rest, making me aware of the pounding. Blood pressure rises slightly. Pulse is 107 bp is 111/71 according to my wrist cuff. I am 5'5" 150 lbs. 48 years old. I have taken thyroid med for 15 years. That is it, I don't smoke. I am concerned I may need to see a dr but the pulse doesn't do this more than 2 or 3 times a day.
