I agree with you. It is so scary. If only we can relax during those extra beats but that's easier said then done. But I think you should get great consolation out of the fact that all your tests are normal. If you took nice deep breaths and slowly exhale it might help you..it is great that you don't get weak or dizzy. That too is consoling. But I hear you. It is so scary but if doctors are not worried about you maybe you should keep that in the back of your mind. Please keep in touch.
