I have had persistent a fib for about seven years. For three years I just given beta blocker and warfarin. I then saw an EP and had several cardioversions with no success so decided to have an ablation which had only a 50% chance of success since I was in a fib so long. I was a fib free for about two years. Had another ablation. This one only lasted three months. More cardioversions. No luck. Was put on Propafenone which seems to be working but I'm afraid of long term side effects. Dr says if I stop I'll go back into persistent a fib and he doesn't think another ablation would work. Has anyone had a third ablation that worked after the first two failed? I'm willing to try since I think ablation is great with very little or no side effects for me. Also, has anyone taken Propafenone for a lone time? I read they are only effective for two or three years.
