Thanks for writing in.
The possibilities are cardiac disease, anxiety
. I would advise you to visit a doctor and get an ECG done, since you have had a previous angioplasty
. If cardiac evaluation comes back as normal, then please be reassured that it might be a case of anxiety.
I would suggest that if anxiety is the cause ,you sign up for yoga/relaxation classes.
Hope this helps.
