Hi. Thanks for your query. Noted your history of palpitations and burping after eating food, pulse is 95, ECG and Cholesterol are normal. You are a male of 34 and was diagnosed as anxiety disorder and had been on anti-anxiety pills in past, no smoking, occasional alcohol intake, 5 9 and 95 kg. Since your ECG is normal and you still have palpitations and there is a history of anxiety disorder, this may be related to the stress and/or anxiety only. But untreated anxiety can also lead to cardiac problems, hence I would advise you the following: Get a full cardiac check up done to confirm. If the cardiac check up is normal and related respiratory problems are not present, go for a consultation of a Psychiatrist to have proper psychological evaluation and proper medical in the form of tablets and para-medical treatment in the form of acupressure, naturo-therapy and so on. You will certainly will be fine.
