So I've always been under the impression that AF could not cause you to flat line at all, even my EP told me that this was the case.
However I've done a little research and found that there have been a few studies which link AF to cardiac arrest. So there is at least a little contradictory literature out there regarding the benign nature of the disease.
Could anyone enlighten me further? I suppose there's always the possibility that the subjects who had cardiac arrest had other heart ailments too.
