The most common associated anomalies are a secundum ASD and a persistent left SVC
draining into the coronary sinus. Most primum ASDs are relatively large and lead to right …

The P wave indices of maximum duration and dispersion have received increasing attention
and have been examined in a broad range of clinical settings. The ECG, as a …

Background Sequential analysis of atrial electromechanical coupling (P‐A) by Doppler
tissue imaging (DTI) might provide important insight into the mechanisms of paroxysmal …

The study aimed to investigate the intermediate-term effects of transcatheter atrial septal
defect (ASD) closure on cardiac remodeling in children and adult patients. Between …

Background and aim: The GORE® CARDIOFORM (GCO) septal occluder is an atrial septal
defect/patent foramen ovale closure device with theoretical advantages over other …

Automatic detection of atrial activity (P waves) in an electrocardiogram (ECG) is a crucial
task to diagnose the presence of arrhythmias. The P wave is difficult to detect and most of …

Background: P‐wave indices of maximum P‐wave duration and P‐wave dispersion have
been examined in a broad array of cardiovascular and noncardiovascular disease states …

Sick sinus syndrome (SSS) is a set of diseases with abnormal cardiac pacing, which
manifests as diverse cardiac arrhythmias, especially bradycardia. The clinical presentation …

Atrial fibrillation (AF) itself creates structural and electrophysiological changes such as atrial
enlargement, shortening of refractory period and decrease in conduction velocity, called …

Although previous studies have documented a variety of electrocardiogram abnormalities in
beta-thalassemia major (β-TM), little is known about P-wave dispersion (PD), an …
