Flecainide
"I am 55 male, my Atrial Fibrillation was getting worse, then on Oct 2012, I did not feel very well, so walked to the ER to have them take a look. Well, they said my heart rate was 170 and irregular, so they kept me there for 2 days, giving me medicine to slow it down. Then discharged with Diltiazem once a day. After 2 months, doc said let's try to fix the rhythm with cardioversion, so he gave me blood thinner for a month, and Flecainide 2 days before the cardioversion. On the day I was supposed to be cardioverted, my heart was back to sinus rhythm due to Flecainide. So doc told me to stay with Flecainide 100mg twice a day. Been 2 months now, feeling good, always in sinus.
Tomorrow going to see doc and ask him if I can go with 50mg twice daily, or entirely off."
