Your "skipped heart beats" could be PVC's (premature ventricular contractions). I developed them, too, and found that mine were caused by taking an alfalfa supplement. After I stopped taking alfalfa, they diminished to only rarely and not as forceful. My husband started getting them when he started taking Ibuprofen. When he stopped taking Ibuprofen, the PVC's stopped. So it could be your medicine/supplements/or food. I believe that stress can also cause PVC's; so if you're stressed, find the cause and try to eliminate it.
