Like you, my AFib is persistent and I also have a pacemaker. The anti-arrhythmia drug I was prescribed was Amiodarone. That was toxic to my lungs, and I have permanent scarring. Since then I have been on Sotalol, Flecainide, and am now on Propafenone. I am still in AFib. They want to do an ablation, but I know so many people that had to have more than one. I am not sure what to do.
