Prediction of the Efficacy of Pulmonary Vein Isolation for the Treatment of Atrial Fibrillation by the Signal‐Averaged P‐Wave Duration

Abstract

The pre-FPD may strongly reflect atrial dysfunction, and thus may be useful for predicting a successful PVI. Shortening of the FPD after the PVI and similar FPD and BAT values suggest that the last component of the FPD represents the activation of the left PVs.
