Thanks Jerry I appreciate your feedback. Looking at this site and seeing how often you respond to people is great. Sounds like you have quite a bit of experience in this scary area.
You didn't identify how the cardioversion was accomplished, electric shock, or medications? In any case, I doubt there is any relationship between a cardioversion of AFib and PVCs. I'd guess being in NSR is better than AFib relative to developing PVCs, and for everything else for that matter.
