Even though, in day-to-day situations, such as when I'm at home or at work, my pulse rate varies between about 75 bpm and 85 bpm, my pulse always races when I'm at the doctor's office.
I am 29 years old now, and have been referred to cardiologists twice over the years, because the primary care doctor found my resting pulse rate to be between 120 and 140 bpm while taking my vitals.
EKGs (taken, of course, in a doctor's office) have always indicated a regular, just highly elevated, rhythm. I guess it's akin to what would manifest if someone were in a highly stressful, "pulse-pounding" situation.
Should I be concerned about this? I feel nervous when I visit the doctor--no matter which doctor it is--but it seems a bit extreme for my pulse to be elevated by almost 70%.
