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 P wave dispersion—one pixel, one millisecond
The electrophysiological activity of the heart is recorded and presented in form of electrocardiogram (ECG). In 1998 the concept of P wave dispersion as the risk factor for atrial fibrillation (AF) recurrence was introduced.

Simulated Obstructive Sleep Apnea Increases P-Wave Duration and P-Wave Dispersion. [PDF]
BACKGROUND:A high P-wave duration and dispersion (Pd) have been reported to be a prognostic factor for the occurrence of paroxysmal atrial fibrillation (PAF), a condition linked to obstructive sleep apnea (OSA).

The effect of recanalization of a chronic total coronary occlusion on P-wave dispersion [PDF]
Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity.

P wave dispersion and maximum P wave duration are independently associated with rapid renal function decline. [PDF]
The P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as noninvasive tools to assess for left atrial enlargement. There are limited studies to evaluate whether P wave parameters are independently associated with decline in ...

Cardiac heterogeneity in patients with chronic urticaria; A perusal of P wave and QT dispersions
Data on how the heart is affected in Chronic Urticaria (CU), a common annoying chronic dermatological disease, is quite limited. The electrocardiographic parameters; P wave dispersion (PWD) and QT dispersion (QTD) have been consistently reported to be ...

Objective The purpose of the study is to evaluate the risks of atrial and ventricular tachyarrhythmia and the risk of right atrial dilatation by using P wave amplitude (Pda) measurement, in patients with Obstructive Sleep Apnea syndrome (OSAS) by using ...

QT dispersion and P wave dispersion in schizophrenia
BACKGROUND: The difference between maximum QT (QTmax) and minimum (QTmin) on electrocardiography (ECG) is known as QT dispersion (QTd). An increase in QTd carries the risk of ventricular arrhythmia and subsequent death.

P-wave dispersion measurement: Methodological considerations
Well-known difficulties in defining P-wave onset and offset may restrict the accuracy and reproducibility of P-wave dispersion measurements. To achieve greater precision in measuring P-wave dispersion, simultaneous digital recording of all 12 ECG leads ...
