I ve had a-fib for 40 years. Started with lone a-fib, in a few years was full blown into daily. 6 to 8 years ago it became daily and extremely pronounced and had my first ablation that reduced incidents by 80 percent. Still constant events, had another ablation one year later with no improvement. Two years later had a pacemaker installed as I flat-lined for 4.5 seconds. Still having too many events. Now what? Another ablation? Not receiving assurances that another ablation will work. In very good health even with a-fib. 77 years old, 5ft 7in, 250 lbs. gym it three times weekly. Again, now what? Thanks for any comment.
