Hi there, I just thought I would give you the answer I got from my EP. I told him that I get a strong flutter and then it feels like my heart stopped. This is the way he explained it. When you have a premature beat, there is a pause before the next beat because there was supposed to be a regular beat in there. Well if you have 2-3 pvc's in a row, then that pause is about 2to3 beats long. So that explains why the flutter is stronger and also why it feels like it has stopped. I dont want to assume that this is your problem, but I know how aggravating this can be so I was hoping that maybe this would give some peace of mind.
