I am a 36 yr old male who has had anxiety since I was 13. My first time I had palpitations was when I was 22and had just finished eating,. For the next 2 years I was terrified to eat, I would go to er while in full out panic get a EKG and said I was fine. I had a echo done that 2 said I was fine. I still was having palpitations aftr eating and doctor put me on zooloft in 1998 and my life changed!!!!After beind on zooloft for over 10yrs my anxiety has come back,I just had a holter monitor done and it came back normal. My question is how can I assure myself it's anxiety and not some type of arrythmia????
