You haven't told us enough about yourself for for us to offer much help. All I can gather from your posts is you have afib, a cardioversion has been suggested, but apparently there's some debate about that for unknown reasons.
How old are you? Are you male or female? What's your afib history? What drugs are you taking? Have you had any procedures such as ablations? We're not mind readers. You need to open up and tell us about yourself.
