Hi! Thank you for your question and welcome to our site.
You are right in saying that your pulse rate is abnormally high. The normal pulse range is only between 60-100 beats per minute. You may have an underlying hormonal
problem commonly due to a hyperactive thyroid disorder
, or there may be something wrong with your internal pacemaker - the sinus
node - which sets the rhythm of the heartbeat.
I suggest that you see an internal medicine specialist so that he/she can do some detailed physical examination and do some diagnostic tests including some blood work and a possible 24hour Holter monitor
(which records your heart's electrical signatures for an entire day).
If you have any further queries, please do not hesitate to ask me.
