Flecainide
"Had atrial fibrillation since 1995. Ocurred once or twicw e a month severe enough to cause me to rest with my body at 45 deg for a couple of hours till it passed. Was on amiodarone and metaprolol. Stopped the beta blockers 2 years ago in favour of flecainide acetate. Have not had a single episode of unusual rythms."
