Generally, PAF which has a PV origin, is treatable with RF ablation, and these days, the
techniques target isolation of the
foci (electrically active cells
in those pulmonary veins...with no, NO, pacemaker requirement. The pacemaker is needed when the ablation is aimed at the AV node (central natural pacemaker) in order to stop your heart from beating too rapidly and erratically. I'm sure your doc was referring to the RF ablation of the foci in your PVs.
