I have palpatations a lot, usually when I'm nervous or haven't slept much. Very rarely I'll have one that makes my whole body (especially my legs) feel weak and just "funny".....Does this happen to anyone else? Does this mean anything? I had a echo last summer and it came back fine.
I am not sure about the weakness part, but I know that anxiety over Palpatations can cause weakness.. if you haven't seen a DR since last summer, I would go again and discuss your concerns with him/her again.. wouldn't hurt.
