Drugs worked for
most of those years, then I had 2 catheter ablations which fixed the afib for
about 4 years. Have had pacemaker for 1 year but still in afib. Now in afib again. Drugs (Warfarin, multaq, carvedilol, simvastatin) don't seem to work. Lately I have no stamina, which prevents me from exercise. Even walking a slight incline is difficult. I have gained weight. (6'1", 220) My electrophysiologist wants to do AV node ablation but I see conflicting stories about it.
