Atrial myopathy is a condition that consists of electrical, structural, contractile, and autonomic
remodeling of the atria and is the substrate for development of atrial fibrillation, the most …

An increased burden of premature atrial contractions (PACs) has long been considered a
benign phenomenon. However, strong evidence of their involvement in the occurrence of …

Background Catheter ablation is an effective treatment for atrial fibrillation (AF,) but
arrhythmia recurrence occurs in a relevant number of patients. Mechanisms of late occurring …

Frequent premature atrial complexes (PACs) are universal in the general population;
however, their clinical significance is unclear. We hypothesize that frequent PACs are …

Early recurrence of atrial arrhythmias (ERAA) after ablation is common and strongly predicts
late recurrences and ablation failure. However, since arrhythmia may eventually resolve in …

Abstract Purpose of Review Excessive supraventricular ectopic activity (ESVEA), in the form
of frequent premature atrial contractions (PACs) and runs of PACs, is commonly observed in …

Silent or subclinical asymptomatic atrial fibrillation has currently gained wide interest in the
epidemiologic, neurologic and cardiovascular communities. The association of brief …

Early recurrences of atrial arrhythmias (ERAA) after ablation are common and predict late
recurrences and ablation failure. However, becausea proportion of patients with ERAA will …

Objectives: The aim of this study was to examine the relationship between residual
premature atrial contractions (PACs) originating from non-pulmonary veins (PVs), which do …

Background The number of atrial premature depolarisations (APDs) is a known risk factor for
atrial fibrillation (AF) recurrence in humans. Objectives To evaluate if the number of APDs …
