I was captured for the first time in AF in August this year and given bisopropol. The next day the dose was reduced from 2.5 to 1.25 as heart had dropped. A week later I was admitted to coronary care with diagnosis "over beta blocked" and taken off the medication with it just to use as a pill in the pocket. Problem being it takes 12 hrs to get in the system so if I hve an episode I'm relying on my heart to really calm down itself. I'm waiting to see if can have flecainide or alternative is ablation which I'm very nervous about. I wonder if cld take 1.25 alternative days of bisopropol ?
