During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from
an investigational procedure to its current status as a commonly performed ablation …

Atrial fibrillation (AF) is an arrhythmia that can occur as the result of numerous different
pathophysiological processes in the atria. Some aspects of the morphological and …

The recommendations listed in this document are, whenever possible, evidence based. An
extensive evidence review was conducted, focusing on 2006 through October 2012 and …

Background—Specific noninvasive signal processing was applied to identify drivers in
distinct categories of persistent atrial fibrillation (AF). Methods and Results—In 103 …

Background—Complex-fractionated atrial electrograms and atrial fibrosis are associated
with maintenance of persistent atrial fibrillation (AF). We hypothesized that pulmonary vein …

Objectives: We sought to test the hypothesis that complex fractionated electrograms (CFAEs)
recorded during atrial fibrillation (AF) could be used as target sites for catheter ablation of …

During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from a
highly experimental unproven procedure, to its current status as a commonly performed …

Background—Atrial fibrillation (AF) can be initiated by ectopic beats originating from the
atrial or great venous tissues. This study investigated the anatomic characteristics and …

Background—The electropathological substrate of persistent atrial fibrillation (AF) in humans
is largely unknown. The aim of this study was to compare the spatiotemporal characteristics …

Computational Mapping of Rotors and Focal Impulses in Human AF. Introduction: The
perpetuating mechanisms for human atrial fibrillation (AF) remain undefined. Localized …
