Hello,
Some people have faster resting heart rates than others. In the office I would typically order an echocardiogram, EKG, thyroid tests, and maybe a stress test depending on symptoms. If you had shortness of breath, I would probably do stress test. If they all came back normal and you had no other symptoms, I would tell you that you just have a faster resting heart rate than what is considered "normal."' This could be because of the the way your autonomic nervous system regulates your heart rate, but there is not a test to determine the cause other than what I mentioned above.
You should be able to decrease your heart rate with a beta blocker or calcium channel blocker. There is not a proven benefit to decreasing your heart rate, so the only important factor is whether it makes you feel better to have a slower heart rate.
I hope this helps. Thanks for posting.
I see that sometimes in clinic. I am usually at a lose for this happens.
thankyou for the reply.i did have echocardiogram and that came back normal.its just that i never used to have a high pulse rate.
