QT dispersion in patients with acromegaly

Endocrine, 2012
Acromegaly is a rare condition caused by a pituitary adenoma that secretes growth hormone. The mortality rate is 72 % higher in patients with acromegaly than in the general population according to meta-analyses. Mortality analysis has shown as many as 60 % of acromegalic patients die due to cardiovascular disease.

Measurement and interpretation of QT dispersion

Progress in Cardiovascular Diseases, 2000
QT dispersion was proposed as an index of the spatial inhomogeneity of ventricular recovery times. The results of studies that found significant correlation between dispersion of ventricular recovery times measured with monophasic action potentials and QT dispersion were interpreted as proof of the direct link between QT dispersion and the dispersion ...

Prolonged corrected QT dispersion

Oncology Reports, 1997
The anthracyclines are antibiotics effective in the treatment of many malignancies. However, their usefulness is limited by the development of potentially acute or chronic cardiotoxicity. No definitive guidelines exist for monitoring cardiac function during and after anthracyclines although methods have been suggested.

Cellular basis for QT dispersion

Journal of Electrocardiology, 1998
The cellular basis for the dispersion of the QT interval recorded at the body surface is incompletely understood. Contributing to QT dispersion are heterogeneities of repolarization time in the three-dimensional structure of the ventricular myocardium, which are secondary to regional differences in action potential duration (APD) and activation time ...

QT intervals and QT dispersion in patients with subarachnoid hemorrhage

Journal of Anesthesia, 2001
To clarify the clinical significance of QT dispersion and the longest QT intervals (L-QTc) in patients with subarachnoid hemorrhage (SAH).ECGs, clinical features, and laboratory data were analyzed in 38 patients with SAH (R) and 30 with unruptured cerebral aneurysms (U).

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 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.
