Dispersion of P wave duration and P wave vector in patients with atrial septal aneurysm [PDF]
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 assessed by P wave dispersion measurement. The aim of this study is to assess the dispersion of P wave duration and P wave vector in patients with ASA and to determine the effect of

P wave dispersion on 12-lead electrocardiography in adolescents with neurocardiogenic syncope [PDF]
PurposeNeurocardiogenic syncope (NCS) is the most frequent cause of fainting during adolescence. Inappropriate cardiovascular autonomic control may be responsible for this clinical event.

The effects of COVID-19 on the heart are still not fully known. In this study, we investigated how COVID-19 affects the P interval. Electrocardiographies (ECG) of 30 COVID-19 patients and the control group consisting of 23 healthy volunteers were examined and dispersion (Pd) of the P wave was calculated.

Electrocardiographic P-wave Indices as a Useful Tool to Predict Successful Percutaneous Balloon Mitral Valvotomy in Patients with Mitral Stenosis [PDF]
Introduction: Patients with hemodynamically significant mitral stenosis (MS) have prolonged P-wave duration and increased P-wave dispersion (PWD) that decreases after successful percutaneous balloon mitral valvotomy (PBMV).

The true nature of P wave dispersion
The electrophysiological activity of the heart is recorded and presented in form of electrocardiography (ECG). In 1998, the concept of P wave dispersion as the risk factor for atrial fibrillation (AF) recurrence was introduced. It was calculated as the difference between the longest and the shortest P wave.To prove that the P wave dispersion is an ...

Effects of haemodialysis on maximum P wave duration and P wave dispersion [PDF]
Analysing a 12-lead surface electrocardiogram (ECG), the inter-lead variability of the P wave interval, i.e. P wave dispersion, is defined as the difference between the maximum and the minimum P wave duration. Our aim was to assess the effect of haemodialysis on P wave duration and dispersion in non-diabetic patients with end-stage renal failure on ...

P-Wave Duration and P-Wave Dispersion in Patients with Dilated Cardiomyopathy [PDF]
Abstract Background P-wave dispersion (PWD) has been reported to be associated with inhomogeneous and discontinuous propagation of sinus impulses. In the present study, we aimed to investigate PWD in patients with dilated cardiomyopathy.
