arrhythmia
"In persistent Atrial Fibrillation for five years. Tried a few cardioversions and they lasted a week or so. I wasn't very symptomatic so I lived with it along with Coumadin and then Pradaxa.  Had ablation, stayed in sinus for 2 weeks. Couldn't tolerate flecanide. Had another cardioversion and would not convert. Put on Tikosyn and spontaneous normal sinus after one dose and no hint of AF since."
