About three years ago I had a panic attack and went to the ER fearing a heart attack. After a chest xray and EKG I was told I had a panic attack. Just to be sure I saw a cardilogist and had a number of EKG's, stress test, blood work, ekg, and a holter moniter. He told me to relax i had a very healthy heart. Well I continue to fear heart problems and check my pulse a lot. The fear has never left me. Days ago after eating I felt a flutter in my heart for a few seconds and started worrying again. No other symptoms or pain. Is that feeling normal? Or do I need more testing?
