atrial fibrillation
"Started flecainide 9 months ago after very frequent episodes of AF. Tried bisoprolol first but suffered side effects and still had AF. Couldn't sleep and sat round like a zombie. Now I take very low dose bisoprolol and 100 mg flecainide twice a day. Life is normal again, but I get a bit breathless with exercise like walking up steep hills! I'm a 62 year old female and was very fit until 5 years ago! At least I now have a near normal life."
