Hi I am new to this web site. I have af and tachicardia. I take 150mg of flecinate, no caffeine, no alcohol, low sugar, and vegan diet. All this helps my symptoms, but at night I wake up at least twice with rapid heart rate. I have had two ablations. I wanted to ask if any one has tried another drug that helps better than flecinate.flecinade gives me real dreams at night that work me up into rapid heart rate.
