QT Dispersion in Sarcoidosis

Chest, 2005
QT dispersion (QTd) is the maximal interlead difference in QT interval on surface 12-lead ECG. An increase in QTd is found in various cardiac diseases. Sarcoidosis augments inhomogeneity in ventricular repolarization by sarcoid granuloma, which significantly correlates with ventricular fibrillation.

QT dispersion in hypothyroidism

International Journal of Cardiology, 1999
Abstract We studied ten women (age: 40±12 years) with primary hypothyroidism. Baseline and after T4 treatment (euthyroid stage), all patients' resting ECGs were recorded. After T4 treatment, QTd ( P =0.036), QTad ( P =0.016), JTd ( P =0.0001), JTad ( P =0.005), Ted ( P =0.036), QRS ( P =0.046), QTcd ( P =0.036), QTacd ( P =0.028), JTcd ( P =0.006 ...

QT interval dispersion: dispersion of ventricular repolarization or dispersion of QT interval?

Journal of electrocardiology, 1998
The QT interval (QTI) has long been useful as a clinical index of the duration of ventricular repolarization, particularly as a marker of prolonged repolarization and its well-established association with arrhythmogenic cardiac states. Likewise, inhomogeneity (dispersion) of repolarization has been linked definitively to increased susceptibility to ...

QT dispersion: An electrocardiographic derivative of QT prolongation

American Heart Journal, 2001
QT dispersion has been considered a surrogate for heterogeneity of repolarization, leading to ventricular arrhythmias.High-resolution 12-lead electrocardiograms were obtained in 15 patients with a history of ventricular tachycardia or ventricular fibrillation, 15 patients with congestive heart failure, 17 patients with a history of previous Q-wave ...

QT Interval and QT Dispersion in Eating Disorders

Psychotherapy and Psychosomatics, 2004
<i>Background:</i> Eating disorders are thought to be risk factors for cardiac sudden death secondary to arrhythmia. Results in previous studies on QT interval and QT dispersion, markers of fatal arrhythmia, have been inconsistent. <i>Methods:</i> We prospectively examined 179 female eating disorder patients, being over 18 years

Significance of QT dispersion in the long QT syndrome

Progress in Cardiovascular Diseases, 2000
The long QT syndrome (LQTS) has often been considered as a model to study the abnormalities of cardiac repolarization in humans because it represents a pure electrical disease with no evidence of cardiac structural abnormalities. The arrhythmogenic potential of prolonged ventricular repolarization has been extensively studied both in experimental ...
