Hi Scooter - I took flecanide for a couple years and was using it as a med. to quickly try and convert me back to sinus rhythm when I went into afib, I'm not sure but don't recall it helping with my PAC's or PVC's, and I've only been on sotolol for a month since my last ablation surgery and it definitely has not done anything for them - it seems to keep my heartrate down and also lowers my blood pressure. Hope this helps. Shawn
