I am on Flecainide; it scares me when I read the warnings though I don't feel any side effects so far, but (and I know I shouldn't do this) I cut the dosage in half and I have had no PACs in the six weeks I've taken it. Who knows if it is really doing any good? I definitely understand your feelings. The EP that I saw was super, though; he thoroughly approves of sites like this where people can ask for feedback and understand they aren't alone in this situation. He said he was part of a support group when he was in training and he learned more about A-fib from listening to patients than he learned in classes. Hang in there!

He may have been the typical busy 'There, there...' responder among physicians who have trouble with empathic interactions. Maybe they're too exhausting for him. Not excusing, more trying to guess why the somewhat distant and cold, 'Fuggedaboutit.'
I'm sure you are reasonably well-informed about your heart's structure and its disordered state. AF won't kill you,.......but....it can take the starch out of a person if that person is symptomatic, as I am. It's just distinctly unpleasant, unnerving, exhausting....people told me that I looked grey. And part of the concern we have is that, although AF won't kill us, it does invite other follow-on conditions that can kill us, so it should be strictly limited in its extent....the number of hours it is allowed to take place. And that is why ablations are the best way to rid the patient of the effects, those being tachycardia, chest wall thumping, loss of sleep, enlarged heart chambers, prolapsed mitral valve, and eventual heart failure.
I am truly sorry to learn that your second ablation has failed. I don't know what I would have done had my second failed, but....fortunately...... Are you in a position to go to another EP? A better one, one who deals with complex cases? If you don't mind some travel, some expense, but want the very best, I can recommend Dr. Andrea Natale at the Texas Cardiac Arrhythmia Institute in Austin. He is one of the best in the entire world. He travels to other hospitals, not just Austin (CA as an example, two or three of them), so maybe you can call and find one close to you and you can be scheduled.
BTW, no cardioversion of my four ever worked for more than 16 hours. The first didn't work at all, and to add insult to injury, I came-to from the propofol just as the technician administered the third most jouled jolt. NOT happy about that!
