Predicting the Arrhythmogenic Foci of Atrial Fibrillation Before Atrial Transseptal Procedure:

Abstract

Endocardial atrial activation sequences from right atrial, His-bundle, and coronary sinus catheters can accurately predict the location of initiating foci of AF before transseptal procedure. This may facilitate mapping and radiofrequency ablation of paroxysmal AF.
