Hi there, I suffer from an anxiety/panic attack disorder and heart palptations are symptoms of anxiety. I get benign palpitations frequently, however, if I start to worry about the palpitations being more than it is, I find I scare myself and sometimes produce a panic attack.
It feels like somethings wrong with your heart and on your mind your thinking your going to have a heart attack and die. This happens to be a symptom of anxiety.
Please remember I am not a physician.
Best of luck and God Bless..........
Kindly,
Kitt
