atrial fibrillation
"I have been on this medicine for about 7 years. I take a large dose, 200 mg twice a day. I previously suffered from PVCs, PACs and Atrial fibrillation. PVCs were the main culprit and they were very bad.  Normal heart.  I was on Sotalol but over time that became less effective and possibly even pro-arrhythmic. The Flecainide has pretty much kept me in normal sinus rhythm since I started taking it with a few breakthroughs. I have also given up caffeine, alcohol, sugar and I now use a CPAP machine for sleep apnea.  I also try and get a minimum of 7 hours of sleep.  Combined with the Flecanide I am virtually free of the heart rhythm problems."
