P-Wave Dispersion in Panic Disorder

Psychosomatic Medicine, 2007
P-wave dispersion (PWD) is defined as the difference between the maximum and the minimum P-wave (Pmax and Pmin, respectively) duration. Significant variation in cardiac atrial PWD has been correlated with changes in systemic autonomic tone such as during periods of anxiety. It is also known that the degree of PWD seen on 12-lead electrocardiogram (ECG)

P wave dispersion in patients with hypochondriasis

Neuroscience Letters, 2010
P wave dispersion (Pd), defined as the difference between the maximum and the minimum P wave duration, has been associated with anxiety. Thus, we wondered whether Pd in hypochondriasis which is associated with anxiety differed from that in healthy controls.

P wave dispersion in familial Mediterranean fever

Rheumatology International, 2010
Familial Mediterranean fever (FMF) is a hereditary disease characterized by recurrent and self-terminated attacks of fever and polyserositis. A recent study found that FMF patients had an abnormally high P wave duration and P wave dispersion, markers for supraventricular arrhythmogenicity.

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.
