Background: Paroxysmal atrial arrhythmias especially atrial fibrillation (AF) are frequently
encountered in adult patients with atrial septal defect (ASD). Previously it was shown that …

Background: Patients with atrial septal defect (ASD) have an increased risk for atrial
fibrillation (AF). Previously it was shown that maximum P wave duration and P wave …

Aims Although atrial fibrillation is a frequent complication of an atrial septal defect (ASD) of
the secundum type, the underlying mechanisms are poorly understood. Atrial conduction …

Background: P maximum and P dispersion are evaluated as predictors of paroxysmal atrial
fibrillation in adults. In this study, these variables are being investigated in children with …

BACKGROUND: In patients with atrial septal defect (ASD) the P-wave is prolonged as a
marker of delayed atrial conduction which is associated with atrial fibrillation. The study aim …

Aims Atrial septal aneurysm (ASA) may be involved in the genesis of atrial arrhythmias as a
consequence of disturbances in the propagation of depolarization, which may be easily …

Atrial conduction disease provides a suitable substrate for reentry and appears to be a major
predisposing factor for the development of atrial fibrillation. It was demonstrated that when …

Objective: The aim of the study was to investigate the relationship between atrial septal
aneurysms (ASAs) and cardiac arrhythmias via signal‐averaged P‐wave duration (SAPWD) …

Background: The prolongation of intraatrial and interatrial conduction time and the
inhomogeneous propagation of sinus impulses are well known electrophysiologic …

Background: Paroxysmal atrial fibrillation (PAF), a common arrhythmia, is caused by the
fractionated and nonhomo‐geneous propagation of sinus impulse. Hypothesis: This study …
