I had this procedure in 2008, some 7years ago. after three attempts to change rhythm to normal, the operation failed ....leaving the hospital I noticed the burn marks on my chest over the heart and directly behind on my back. Proceeding the operation I was explosive, my physical ability was up there. Since leaving the hospital til now 2015 my health is absolute shot......My Doctors are telling me now that my heart has been subjected to abuse. My heart was not subject to abuse, maybe a touch to much sugar and salt, but I've seen the intake of others. I wonder to myself if maybe the failed cardioversion maybe be responsible for the deterioration, my health has nose dived since leaving the hospital...
