QT and JT Dispersion in Children with Long QT Syndrome

Journal of Cardiovascular Electrophysiology, 1997
QT and JT Dispersion in Long QT Syndrome. Introduction: Abnormalities of ventricular repolarization leading to ventricular arrhythmias place children with long QT syndrome at high risk for sudden death. Dispersion of the QT (QTd) and JT (JTd) intervals, as markers of cardiac electrical heterogeneity, may be helpful in evaluating children with long QT

Long QT interval syndrome with increased QT dispersion

Acta Anaesthesiologica Scandinavica, 1997
This case report describes the anaesthetic management of a patient with sporadic‐type long QT interval syndrome (LQTS), and increased QT dispersion, who presented for removal of an ovarian cyst. Beta adrenergic blockade and adequate depth of anaesthesia for successful management is emphasized. The Successful use of epidural administration of lignocaine

Abnormal QT dispersion in Behçet's disease

International Journal of Cardiology, 1997
Behçet's disease, which was originally described by Hulusi Behçet in 1937, is a generalized chronic inflammatory disease characterized by recurrent oral and genital ulcerations, ocular and dermal manifestations. Cardiac manifestations include pericarditis, myocarditis, conduction system disturbances, coronary arteritis, mitral valve insufficiency ...

QT Dispersion in Renal Transplant Recipients

Nephron, 2002
An increased QT dispersion (QTd) is associated with a variety of cardiac diseases and predicts sudden death. Although chronic renal failure patients and patients on hemodialysis are shown to have an increased QTd, evidence of increased QTd in renal transplant patients is scarce.

[QT dispersion].

Przeglad lekarski, 1997
The study presents the modern concepts on QT dispersion which is regarded as one of the reasons of potentially dangerous cardiac arrhythmias. The measurement of QT interval is based on standard 12-lead electrocardiogram or 24-hours Holter monitoring record.

QT dispersion in the elderly. The ILSA Study

Aging Clinical and Experimental Research, 2004
In the last few years there has been active interest in the study of QT interval dispersion (QT-d) calculated from the 12-lead ECG, as a non-invasive method of investigating the homogeneity of ventricular recovery time. The aim of this study was to evaluate QT interval dispersion, analyzing in particular gender and age relationships.

QT Dispersion in Hemodialysis and CAPD Patients

Nephron, 2002
Prolongation of repolarization dispersion (QT interval dispersion) measured from the 12-lead surface ECG has been associated with sudden cardiac death and ventricular tachyarrhythmias in a variety of cardiac disorders. The aim of our study was to assess the effects of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) on QT ...

QT Dispersion and Rate-Corrected QT Dispersion During Electroconvulsive Therapy in Elderly Patients

The Journal of ECT, 2011
Electroconvulsive therapy (ECT) induces increase of QT dispersion (QTD) and the rate-corrected QTD (QTcD), which are associated with increased risk of ventricular arrhythmias and cardiovascular mortality. The effects of electrical stimulus during ECT on QTD and QTcD in elderly patients are of considerable interest.The purpose of this study was to ...

Spatial Distribution of QT Intervals: An Alternative Approach to QT Dispersion

Pacing and Clinical Electrophysiology, 1996
QT dispersion (QTd) describes the heterogeneity of ventricular repolarization on the basis of the temporal range of QT intervals as measured in the 12‐lead ECG. We examined the spatial distribution of QTd using multichannel magnetocardiograms (MCGs), which noninvasivety register changes in magnetic field strength at 37 sites over the heart.

QT interval and QT dispersion in systemic sclerosis (scleroderma).

Journal of internal medicine, 1998
To measure QT interval and QT dispersion, and to evaluate possible relationships between these measurements, heart rate variability parameters, and early myocardial involvement in patients with systemic sclerosis (SSc).Prospective study.Tertiary care centre, University 'La Sapienza', Rome, Italy.Thirty-eight patients with SSc (35 females and three ...
