Hello. I have been having heart palps for over a month off and on. I have been to the emergency room twice they did tests ekg normal, blood work normal, diagnosed it as stress. I then went to see a cardiologist the same tests were done couldn t find anything, just stress related. My cardiologist has me wearing a heart holter for 30 days, and I am getting frustrated because i do not know what is causing the heart palps. They keep telling me they are harmless, but sometimes I feel like they are controlling my life.
