I've heard the Cleveland Clinic is the leader in this type ailment and ablation surgery. I guess I might be getting one at some point in the future. Right now I take Flecainide and Atenelol, and lots and lots of Magnesium. This has reduced my episodes from twice a week for 24 hours each to, about once every two weeks for 4 to 6 hours. I can live with this now but, these things generally don't get better as time moves on.
