P Wave Dispersion Increases during Hemodialysis Sessions

Nephron Clinical Practice, 2009
<i>Background/Aims:</i> Atrial fibrillation (AF) is common among hemodialysis (HD) patients and is associated with high mortality. P wave dispersion (PWD) is a noninvasive electrocardiographic marker of paroxysmal AF. Our aim was to evaluate the effect of HD session on PWD. <i>Methods:</i> Twenty-five patients (mean age 63 years,

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

AB0862 Qt Dispersion and P Wave Dispersion in Fibromyalgia

Annals of the Rheumatic Diseases, 2014
Background Fibromyalgia syndrome is a chronic disease with unknown etiology, characterized by widespread pain. QT dispersion represents a general repolarization abnormality and autonomic dysfunction. Longer QT dispersion is associated with higher risk of ventricular arrhythmias, cardiac events and mortality.

Effect of Birth Asphyxia on P Wave Dispersion

The Indian Journal of Pediatrics, 2013
To evaluate the cardiac conduction system using P wave dispersion on electrocardiogram and its relationship with the short term mortality and development of arrhythmia in asphyxiated neonates.Thirty term babies with evidence of asphyxia and without any congenital abnormalities were consecutively evaluated as cases.

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 transcatheter aortic valve replacement on P-wave duration, P-wave dispersion and left atrial size

Journal of Geriatric Cardiology, 2015
Background P-wave dispersion (PWD), a measure of heterogeneity of atrial refractoriness, is defined as the difference between the maximum and minimum P-wave duration.

Coronary Collateral Circulation: Any Effect on P-Wave Dispersion?

Angiology, 2008
Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between coronary collateral circulation and arrhythmia risk.

Assessment of P wave duration and P wave dispersion in high level football referees

The Journal of Sports Medicine and Physical Fitness, 2017
P wave dispersion and P wave maximal duration reflect the activation of atrial muscle and is influenced by the mass of the excited tissue. It may reflect atrial remodelling, most likely atrial fibrosis. The purpose of this study was to measure P wave duration and P wave dispersion in the high level football referees.We recruited 104 elite and national ...
