atrial fibrillation
"I had an episode of atrial fibrillation once in 1979, once in 1999 and once in 2009. A cardiologist then said I was to take Flecainide if I had another episode.

I woke up one night in 2011 with atrial fibrillation so I waited one hour as instructed and then took two Flecainide tablets, The fibrillation stopped an hour after I took the tablets.There were no side effects.

Another cardiologist has recommended that I take Flecainide and the blood thinner Pradaxa next time atrial fibrillation occurs."
