I have been having heart palpatations and some belching.  had a EKG and saw a cardiologist who felt it was anxiety.  I lost my best friend of 26 yrs this past year and also went through a divorce.  I started taking pepcid ac and that has pretty much taken away the palpatations and I have been walking 20 min a day.  Just hope this is not heart related. Thank you
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about major heart diseases because your ECG is normal. You are mostly having stress and anxiety related symptoms. These can cause acute gastritis, palpitations, belching etc. Your symptoms are improved with antacid Pepcid. It is 100% stress and anxiety. Better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.
