I have had my heart skip a beat.. It will beat consistently and then all of a sudden it will stop.. then it will continue to beat and then stop.. When it stops I feel a flutter sensation. I tried to back off on the caffeine.. It seemed to subside, but I am concerned as it still is doing it. I don't have the energy to want to work out and I find I'm tired quite often. I went to a cardiologist a couple months ago, and he did nothing. Of course, my heart was beating just fine then. My cholesterol is 205 and I am working on diet to bring it down. With oatmeal and flaxseed every day. I am 60 years old and I would think there would be some tests to make sure my arteries are not clogged.. I am not sure what to do next..
