I'm 53 with no heart disease and have been on daily flecanide (100mg x3 daily - I'm 6'6" and 16 stone hence the large dose) and 2.5mg of bisoporol. I get an AFib break through almost everyday, normally if I am late taking my flecanide. However the incidents are very low level - 80-90 bpm, mildly irregular, almost no symptoms and last no more than 2 hours but most commonly 15-30 mins. The arrhythmia nurse is really pleased as is my cardiologist as this regime is only to get me to ablation. I would rather try an alternate rate control drug as although the incidents don't affect my quality of life - I'd still rather have fewer.
Any one experience similar and if so, did you try another drug.
