Ever since then I have been having horrible palpitations that go beat..stop..beat..stop or beat, beat..stop.. beat,beat..stop. does anyone experience this? Since I can hardly functiom.because of how feequent these are and have severe anxiety from it. I jave been to many, many doctors and every one says it's normal and I'm going to be fine. I feeling I .going to die and it takes my breath away. Is there anyone else who.has this? Please help!!!
