P wave dispersion and maximum P wave duration are independently associated with rapid renal function decline. [PDF]

PLoS ONE, 2012
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 ...

Usefulness of P Wave Duration in Embolic Stroke of Undetermined Source. [PDF]

J Clin Med, 2020
The investigation of the potential association between ischemic stroke and subclinical atrial fibrillation (SCAF) is important for secondary prevention. We aimed to determine whether SCAF can be predicted by atrial substrate measurement with P wave signal-averaged electrocardiography (SAECG). We recruited 125 consecutive patients with embolic stroke of

P‐Wave Duration and Dispersion in Obese Subjects [PDF]

Annals of Noninvasive Electrocardiology, 2008
Background: Although previous studies have documented a variety of electrocardiogram (ECG) abnormalities in obesity, P‐wave alterations, which represent an increased risk for atrial arrhythmia, have not been studied very well in these patients. The aim of the present study was to evaluate P‐wave duration and P dispersion (Pd) in obese subjects, and to

Increased P Wave Dispersion and Maximum P Wave Duration after Hemodialysis [PDF]

Annals of Noninvasive Electrocardiology, 2004
Background: Atrial fibrillation is a frequent arrhythmia in patients undergoing hemodialysis. The consequences of hemodialysis on P wave durations and P wave dispersion have not been fully understood. The objective of this study was to study the effect of dialysis on P wave maximum (Pmax), P wave minimum (Pmin), and P wave dispersion (Pd). Methods: We

Increased P‐Wave Duration and P‐Wave Dispersion in Patients with Aortic Stenosis [PDF]

Annals of Noninvasive Electrocardiology, 2003
Background: P‐wave dispersion (PWD), defined as the difference between the maximum and minimum P‐wave duration, has been proposed as being useful for the prediction of paroxysmal atrial fibrillation (AF). AF is the most common arrhythmia and an important prognostic indicator for clinical deterioration in patients with aortic stenosis (AS).

P wave duration in paroxysmal and persistent atrial fibrillation [PDF]

Advances in Clinical and Experimental Medicine, 2020
Functional and structural changes in atrial muscle constitute a substrate for atrial fibrillation. The pathological changes in the left atrium decrease conduction velocity and result in prolongation of the P wave duration. The aim of the study was to assess the duration of the P wave in patients with paroxysmal and persistent atrial fibrillation.

P-wave duration as a marker of atrial remodeling in patients referred to ablation for atrial fibrillation: A new stratification tool emerging?

Hellenic Journal of Cardiology, 2023
Ablation of atrial fibrillation is one of the most widely applied invasive procedures in cardiovascular medicine, and populations with atrial fibrillation continuously rise.

P Wave Indices—Advancing Our Understanding of Atrial Fibrillation-Related Cardiovascular Outcomes

Frontiers in Cardiovascular Medicine, 2019
Atrial fibrillation (AF) is associated with an increased risk of ischemic stroke, heart failure, cognitive decline, dementia, myocardial infarction, sudden cardiac death (SCD), and all-cause death.

Electrocardiographic predictors of early recurrence of atrial fibrillation

Annals of Noninvasive Electrocardiology, 2021
Background Electrical cardioversion (ECV) is an effective method for restoring sinus rhythm after atrial fibrillation (AF). However, early recurrence of AF occurs in a significant number of patients after ECV.
