Thanks for your reply cindy. I've thought about having the EP study done, but I have it so infrequently. The cardiologist said it was nothing dangerous, just a nusance. I happened to me every night about 4 years ago for a couple of months then didn't start happening again till a few months ago and after that few months it's not happening now. If it hits me then hangs around, I might have to do the ablation b/c of the interruption in sleep it causes. It's frightening as well, even when you know what's going on.
