P wave dispersion in obsessive-compulsive disorder. [PDF]
Indian J Psychiatry, 2015 P wave dispersion (Pd) is defined as the difference between the maximum and the minimum P wave duration. It has recently been associated with increased anxiety levels, thereby predisposing affected individuals to fatal heart disease. Despite of evidence of this autonomous nervous system (ANS) relationship, there are no electrocardiography (ECG) studies

Dispersion of P wave duration and P wave vector in patients with atrial septal aneurysm [PDF]
Europace, 2007 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]
Korean Journal of Pediatrics, 2016 PurposeNeurocardiogenic syncope (NCS) is the most frequent cause of fainting during adolescence. Inappropriate cardiovascular autonomic control may be responsible for this clinical event.

Eastern Journal Of Medicine, 2022 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]
Journal of Cardiovascular and Thoracic Research, 2014 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
Advances in Clinical and Experimental Medicine, 2020 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 ...
