Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
BACKGROUND In inflammatory bowel disease (IBD) number of thromboembolic events are increased due to hypercoagulupathy and platelet activation. Increases in mean platelet volume (MPV) can lead to platelet activation, this leads to thromboembolic events and can cause acute coronary syndromes. In IBD patients, QT-dispersion and P-wave dispersion are predictors of ventricular arrhythmias and atrial...
OBJECTIVES This study tested the correlation of QT and JT dispersion and other potentially useful electrocardiographic (ECG) indexes with dispersion of repolarization and recovery time. BACKGROUND Dispersion of ventricular repolarization is currently being assessed noninvasively from the surface ECG by means of QT and JT dispersion, although their correlation with dispersion of repolarization...
BACKGROUND This study determined whether dispersion of conduction velocity, refractoriness, or excitability increases biphasic shock defibrillation energy requirements (DERs). METHODS AND RESULTS Twenty-four swine were instrumented with a mid-LAD perfusion catheter for regional infusion of lidocaine 0.75 mg. kg(-1). h(-1) (n=7), low-dose d-sotalol (0.16 mg. kg(-1). h(-1)) (n=4), high-dose d-s...
Introduction: QT dispersion in a 12 lead ECG represents the heterogeneity of ventricular repolarization. The prolongation of QT-interval dispersion increases the risk of coronary heart disease, ventricular arrhythmia, and sudden cardiac death in patients with myocardial infarction. We aimed to investigate the prognostic value of QT-dispersion in patients with acute myocardial infarction. Meth...
