Assessment of Pulmonary Vein Isolation by Local Potentials in FARAPULSE Pulsed Field Ablation System

Herein, we propose a novel approach examining intra-spline bipolar potentials-rather than conventional cross-spline potentials-using the FARAWAVE catheter to assess pulmonary vein isolation in the FARAPULSE pulsed field ablation system. The novel intra-spline bipolar electrograms on the FARAWAVE catheter are useful for reducing far potentials during confirmation of the pulmonary vein isolation line.
