I also get palpitations have done for years. It is very frightening, it still frightens me after after all the tests and the Drs telling me there is nothing wrong with my heart. I also get headaches and a light headed feeling, I know it is just another thing we have to put up with but things do get better, I no longer get D very often, and in time the palpitations get less. Try relaxation tapes or meditation it helps me a great deal. It also helps to know I am not alone, so remember you have friends who know what it's like. Stick with it, you'll get there.
