Not sure. I was, until that evening, a patient with AF. The flutter, as I said, was news to me. It didn't seem to manifest at any other point in the months ahead, nor did it appear in any record that I became cognizant of prior to that evening. The gentleman told me that flutter tends to stay in flutter, while AF, especially paroxysmal, comes and goes. Yet, after a cardioversion, I went home and was free of any ectopy for about 16 hours. Then, after three hours in AF, back to the ER. Next day as well. The treatment was only a bolus of metoprolol. The third day, they sent me home and said to hope I converted. I did, within an hour or two, and had my second ablation about 13 days later.

i don't know if flecainide or amiodarone would convert flutter.
