Hello and thanks for the query
I would like to know whether high heart rate
is constant or you get an episode after an interval?
Have you done EKG at the time of high heart rate?
If it is episodic than how frequent it occur?
The cause of high heart rate are:
1. Anxiety: Every person has stress
in life but its how the person react to it. So relax your mind as much as you can by exercise or yoga
2. Heart related problem: PSVT
or AF can cause this. EKG at the time of episode can diagnose it. It is well treated by medication. Consult your doctor for that.
3. Hypothyroidism: Check your thyroid function test.
Hope this will help you.
