I'm 47yo, 6'1" 220lbs. In relative good health and get around fast. My EP says I have this condition sometimes. I will be seated on my couch for awhile, then stand, and my HR has shot up to 145bpm recently with major palpitations. Also when I go up one flight of stairs at work very slowly, my HR rises quickly to 120+. I find this "inappropriate" and concerning. One day I was at the gym, and the gym instructor said it was abnormal for HR to climb so quickly. He said going up one flight of stairs slowly shouldn't raise it to 120+ so quickly.
I'm on Multaq for AFIB, Bystolic 2.5mg, and Xarelto for past DVT/PE's. I had a recent EKG and Echocardiogram done, and both normal. But it seems like the past few months, my resting heart rate has risen. It used to be 50-60 and now it is 70-80. And when I do any considerable effort, it raises to the triple digits 130+ very quickly.
Also after any sort of activity, my resting heart rate remains elevated at around 100 for a few hours or more. It never comes down, even if i sit down for a few hours. The only time it will come back down, is when i take my Multaq and Bystolic at night.
Should I be concerned or should I believe my cardiologist and EP that everything is fine?
