P Wave Dispersion in Children with Breath-holding Spells

open access: yesTürk Nöroloji Dergisi, 2016
Objective: A breath-holding spell (BHS) is a clinical feature frequently seen in infancy and early childhood and generally bringing children to pediatric cardiology outpatient clinics with the suspicion of cardiac disease.

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

open access: yesAnnals 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).

Wave Dispersion Behavior in Quasi-Solid State Concrete Hydration

open access: yesSensors, 2023
This paper aims to investigate wave dispersion behavior in the quasi-solid state of concrete to better understand microstructure hydration interactions. The quasi-solid state refers to the consistency of the mixture between the initial liquid–solid stage

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

open access: yesAnnals 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

P wave dispersion and severity of obstructive sleep apnea syndrome

open access: yesEgyptian Journal of Chest Disease and Tuberculosis, 2014
Background: OSA is associated with an increased prevalence of coronary artery disease, heart failure and rhythm disturbance. Also, P-wave dispersion (Pd) reflects inhomogeneous atrial depolarization secondary to insults such as chronically elevated ...

Constraints on Crustal P Wave Structure With Leaking Mode Dispersion Curves

open access: yesGeophysical Research Letters, 2021
Classic surface wave imaging relies mainly on the dispersion of Rayleigh waves or Love waves. In addition to these types of waves, waveforms that arrive prior to the S wave also exhibit dispersion. These early dispersed waves are controlled mainly by the

Effect of no-reflow/reflow on P-wave time indexes in patients with acute myocardial infarction undergoing percutaneous coronary intervention

open access: yesInternational Journal of the Cardiovascular Academy, 2020
Aim: The aim of this study was to investigate the relationship between no-reflow (no-RF), reflow (RF), and the P-wave time index in patients undergoing percutaneous coronary intervention (PCI) with a diagnosis of acute myocardial infarction (AMI) due to ...

The Effect of Exercise to P Wave Dispersion and Its Evaluation as a Predictor of Atrial Fibrillation

open access: yesAnnals of Noninvasive Electrocardiology, 2003
Aim: Prolongation of P wave time and increase of its dispersion as an independent predictor of atrial fibrillation. In patients with paroxysmal atrial fibrillation (PAF) as in healthy people, exercise augments sympathetic activity and therefore can cause

The effects of iron deficiency anemia on p wave duration and dispersion

open access: yesClinics, 2010
OBJECTIVES: The association between P wave dispersion and iron deficiency anemia has not been documented in the literature. In this study, we evaluated P wave dispersion in patients with iron deficiency anemia and the possible relationships between P ...
