2 Arrhythmogenic substrate stratification of posterior left atrial wall in atrial fibrillation versus sinus rhythm in persistent atrial fibrillation using automated voltage analysis

Abstract

IntroductionPulmonary vein isolation (PVI) remains the main procedural target in atrial fibrillation (AF) ablation. The posterior left atrial (LA) wall contains multiple potential mechanisms that can initiate and sustain persistent...
