Hello Kay, I used to be worried just like you. Over the years had I numerous EKG's, echocardiograms, hospital visits, etc. etc., they could never find anything wrong with me but I was always convinced that the doctors were wrong and missing something. But here I am years later, still alive. I figured if the pulps were going to kill me they would have by now. Several years from now when you look back and you will see what I mean. Don't go through the years (like I did) worrying if the palpitations are going to kill you because they are not.
