Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, we should first rule out
arrhythmia and other heart diseases in your case.
So get done
1. Ecg
2. 2d echo
3. Holter monitoring (24 hour continuous monitoring of ecg).
If all are normal than no need to worry for heart diseases.
Stress and
anxiety can cause similar symptoms.
So better to
consult psychiatrist and get done counseling sessions, try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs too.
So avoid stress and tension, be relax and calm.
Don't worry, you will be alright.
But first rule out heart diseases.
Hope I have solved your query.
Wish you good health. Thanks.
