atrial fibrillation
"I have had Atrial Fibrillation for about 15 years with episodes about 4 times a year.  These episodes would last from a few minutes to 8 hours.  I was taking Cartia XT during this period with some success.  My doctor just put me on Flecainide because I want to live my life without any episodes. I have gone about a month and things are going well.  The frequent flutters are gone and I have not had a full blown episode at all.  I do not have any side effects.  I am 59 years old, healthy, and very active."
