For nearly 2 years now I've had the sensation of skipped heart beats. Usually after every 3rd beat. Cardiologist tells me it's because the 3rd beat is occurring too soon which increases the interval between that and the next beat. What he has been unable to tell me is why this happens or how to correct it. I've had more expensive tests than I can remember, all coming back negative. I tried medication to slow the heart rate which seemed to work for a while, but than the sensation returned. I tried changing my diet. This too worked for a while, but ultimately the symptoms returned. I even tried vitamin supplements. Same result. Doctor says it's nothing to worry about, but it's really hard not to. Has anyone else had this problem and what has been done about it?
