BACKGROUND This study was performed to determine the changes in corrected QT (QTc) and QT dispersion and their relationship with end-stage liver disease score in the children undergoing orthotopic liver transplantation. METHODS This case-control study was performed in a 2-year period from February 2009 to March 2011 in Department of Organ Transplantation of Nemazee Hospital. We consecutively ...

Background Coronary artery ectasia (CAE) is defined as a diffuse dilatation of the diameter of the ectatic segment of the coronary artery, 1.5 times greater than that of the adjacent segment. The Tp-Te interval, P-wave and QTc dispersions are relatively new electrocardiographic markers associated with an increased risk of developing arrhythmias. Despite CAE increasing in prevalence in recent ye...

OBJECTIVE Obstructive sleep apnoea (OSA), atrial fibrillation (AF) and sudden cardiac death (SCD) may occur concomitantly, and are of considerable epidemiological interest, potentially leading to morbidity and mortality. Effective treatment of OSA with continuous positive airway pressure (CPAP) could prevent progression and/or recurrence of AF and factors leading to SCD. Recently, a randomised ...

BACKGROUND Ventricular arrhythmias are common in patients with mitral valve prolapse (MVP). Previous studies have provided evidence that a higher degree of systolic mitral valve displacement and the presence of a thickened anterior mitral leaflet are related to an increased incidence of complex ventricular arrhythmias and risk of sudden death in these patients. The aim of our study was to inves...

OBJECTIVE To examine the left ventricular regional wall motion abnormality and to evaluate dispersion of this abnormality in patients with long QT syndrome. DESIGN Left ventricular short axis images at basal and middle levels were recorded on videotape and digitised to reconstruct digitised M mode echocardiograms, from which left ventricular wall thickness curves were obtained. The wall thick...

Objectives. This study was planned to evaluate the relation between QT dispersion (QTd) and multi-vessel coronary artery disease in acute coronary syndrome. Methods. Two hundreds and twenty-five consecutive patients with a diagnosis of non-ST segment elevation acute coronary syndrome were included. Three groups were defined as a single vessel, two vessels, and three vessels. Echocardiographic, ...
