For the past 8 years, there has been significant stress in my life. I am often told that my pulse is fast but doctors have never sent me for further testing. My blood pressure is great. My typical HR is around 100 BPM but has gone up to 109. I notice if I am distracted and not thinking about the troubles in my life, my HR goes down by 12 beats within 10 minutes. Does this still indicate tachycardia? I am 57 years old, 5'5" and weigh 130 lbs.
