Duration of the normal P wave

The American Journal of Cardiology, 1959
Abstract Accurate use of the P wave in electrocardiographic measurernent and in electrocardiographic timing of physiologic events requires prior study in each individual to determine the lead with the maximal P wave duration. Magnification of electrocardiographic waves is useful to determine their duration.

Duration of the P Wave and P Wave Dispersion in Subclinical Hyperthyroidism

Endocrine Practice, 2003
To determine whether the values for P wave dispersion (Pdis) and adjusted Pdis, which are simple noninvasive electrocardiographic markers to detect paroxysmal atrial fibrillation, differ in patients with endogenous subclinical hyperthyroidism in comparison with those in healthy control subjects.We measured the maximal P wave duration and the difference

Circadian Behavior of P-Wave Duration, P-Wave Area, and PR Interval in Healthy Subjects [PDF]

Annals of Noninvasive Electrocardiology, 2001
Background: The prolongation of P‐wave duration has long been shown to indicate the presence of high risk for atrial fibrillation. The circadian variation of P‐wave characteristics and their dynamic adaptation to heart rate changes was not tested before.Methods: To evaluate the diurnal pattern of P‐wave duration, P area, and PR interval and of their ...

P-wave duration changes and dispersion in preeclampsia

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2014
The purpose of this research was to study P wave parameters to determine the association between preeclampsia and future cardiovascular risk and to study the possible correlation between P waves and severity of preeclampsia.In this case-control study 58 pregnant women with preeclampsia and 30 normal pregnant women were compared by measuring maximum and

P wave duration and dispersion in multiple sclerosis

Clinical Autonomic Research, 2005
Multiple sclerosis (MS) has been reported to be associated with extensive autonomic dysfunction as well as to involve the cardiovascular system. In this study we compared P wave duration and dispersion (PWD) of MS patients to healthy control subjects.Thirty-one MS patients (mean age 35 +/- 9 years) and 33 healthy control subjects (mean age 34+/-7 years)

Effect of Diuresis on P‐Wave Duration and Dispersion

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, 2002
Study Objective. To evaluate the effects of changing volume status on P‐wave duration and dispersion in patients with decompensated heart failure.Design. Prospective analysis.Setting. Hospital cardiology unit.Patients. Twenty‐one patients with symptoms of decompensated heart failure who were treated with diuretics on admission.Intervention. Twelve‐lead

The Effect of Atrial Fibrillation Ablation Techniques on P Wave Duration and P Wave Dispersion

Heart, Lung and Circulation, 2019
A reduction in surface electrocardiogram (ECG) P wave duration and dispersion is associated with improved outcomes in atrial fibrillation ablation. We investigated the effects of different ablation strategies on P wave duration and dispersion, hypothesising that extensive left atrial (LA) ablation with left atrial posterior wall isolation would give a ...

Relationship Between P-Wave Duration and the Risk of Atrial Fibrillation

Expert Review of Cardiovascular Therapy, 2018
P-wave duration (PWD) is an electrocardiographic (ECG) marker reflecting atrial conduction, and studies have shown that its prolongation is associated with atrial fibrillation. Areas covered: This review addresses the relationship between PWD and atrial fibrillation, how anatomic and physiologic changes in the atria potentiate the risk for atrial ...

Metabolic syndrome and P-wave duration in the American population

Annals of Epidemiology, 2020
Metabolic syndrome has a high prevalence in the United States. P-wave duration is a valuable indicator for atrial electrical conduction. Abnormalities in atrial electrical conduction can predispose to atrial fibrillation. Our objective was to estimate the effect of metabolic syndrome on P-wave duration in a nationally representative sample.We included ...
