I had my third ablation the end of May. It seems to be a failure as I went into afib about 2 days after the ablation. I had a cardioversion the end of July, put me in sinus rhythm for only 2 days. I had another cardioversion one week ago and was in NSR until last night. I am taking Coreg and propafanone, plus xarelto. I've been fighting afib since 2010 and it's really discouraging. I stay away from alcohol and caffeine. Try not to eat big meals. I guess I'm just discouraged that nothing seems to work for me. I had an echo 2 weeks ago which showed severe left atrial enlargement and an ejection fraction of 40-45. The doctor thought the coreg would help strengthen my heart. So I'm wondering if anyone has an internal defribrillator and what it's like? I'm wondering if my EP will suggest this as the next step.
