It wasn't Me asking about ablation n it was Ted, but since you asked I've had somewhere between 8-10 ablation of both interior and external. I have had 2 pacemakers/recorder/ defibulator since my arrhythmia could kill me in a few minutes if the pacemaker could not get my heart rate down from the 200s in a short period it would shock me which it did on many occasions. But that's a long 10 year story. My longest ablation over 5 hours with 4 seperate leads in my heart and my shortest was about 2 hours.
