What are some causes for extra heart beats that make you feel bad? I have been seeing a heart doctor about this problem and have had tests, plus worn a heart monitor several weeks, but the doctor and the results from the tests say that there is nothing wrong with my heart. The monitor picked up on extra beats sometimes, but the doctor says this is normal and thinks it is all in my mind. However, when this happens to me, I feel really bad. Something must be causing this problem, but no one can tell me what I need to do to fix it.
