Atrial fibrillation (AF) is frequently initiated from the pulmonary veins (PVs), but little is known
about the electrophysiological properties of PVs. In total, 77 patients (58 males; mean age …

Atrial fibrillation (AF) is the most common supraventricular arrhythmia. In AF, the irregular
cardiac rhythm is associated with intra-atrial blood stasis, subsequent thrombus formation …

Conclusions Relevant improvement on the knowledge of the electrophysiological basis of
genesis and maintenance of AF has been done in order to treat a very common arrhythmia …

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia and is associated with
an increased risk of stroke, heart failure, and mortality (1). The number of patients affected is …

Atrial fibrillation (AF), the most common arrhythmia, is associated with increased morbidity
and mortality. 1, 2 Although new concepts of AF pathophysiology have emerged, underlying …

Atrial fibrillation (AF) is the most common progressive cardiac arrhythmia, characterized by
rapid and irregular beating of both right and left atria. Its prevalence in Western countries is …

AF is a difficult disease to treat because of the numerous (ischemic, metabolic, inflammatory,
structural) mechanisms contributing to its etiology. AF persistence requires both an …

Identification of atrial sites that perpetuate atrial fibrillation (AF), and ablation thereof
terminates AF, is challenging. We hypothesized that specific electrogram (EGM) …

The electrophysiology of atrial fibrillation (AF) has always been a deep mystery in
understanding this complex arrhythmia. The pathophysiological mechanisms of AF are …

Atrial fibrillation (AF) is the most common cardiac arrhythmia despite substantial efforts to
understand the pathophysiology of the condition and develop improved treatments …
