atrial fibrillation
"I have been taking flecainide for over a year now, for atrial fibrillation. I also have had PVC's all my life.  I have not had one episode other than a few flutters now and then since taking it.  I take 50mg twice a day.  The only negative aspects are some dizziness on occasion (usually when turning my head too quickly) and the fact that I don't like taking pills!  I do occasionally forget to take them.  That is my one big problem, remembering to take them on schedule.  I worry about that."
