I had an ablation two weeks ago, and after my follow up visit and a 24 hour Holter, I was started on Flecainide to treat not my AFIB, but residual arrhythmias that evidently persist. My EP said I might only need it during the "blanking period", which is several months post ablation. The surgery was four and a half hours under general anesthesia, so I don't think it is unusual I still feel pretty listless, but no worse because of the Flecainide I don't think No better either though, but it is still early, so we'll see.
