Hi. I have been suffering from chest discomfort, mild left chest pains, intense fear and panic episodes, and constant heart palpitations for a few weeks now. I went to my GP and he did an EKG. Said my heart was slightly arrhythmic. I am super scared of sudden death. He put me on metaprolol, Xanax, and celexa. What else would you recommend? How likely am I to have sudden death? I'm 30, non smoker, no alcohol, very overweight, somewhat active. I really would like to have a complete check by a cardiologist, but I have no insurance.
