I don't think the dizziness and clammy hands are from anxiety because it happens at the exact same time as the palpitations. I used to get extremely anxious from them, but I have gotten much better about accepting them. It's just a wierd feeling and while I have learned to live with them for the most part, there are times that I think I'm a goner! It feels like it's never going to go back into a regular rythm.
