Preprocedural Screening Tool to Guide Nonpulmonary Vein Trigger Testing in First-Time Atrial Fibrillation Ablation

Patients undergoing first-time atrial fibrillation (AF) ablation can benefit from targeting non-pulmonary vein (PV) triggers. Preprocedural identification of high-risk individuals can guide planning of ablation strategy. This study aimed to create a preprocedural screening tool to identify patients at risk of non-PV triggers during first-time AF ablation.
