Abstract

Relationships Between QTc Interval, QT Dispersion, Systolic Ejection Time and Left Ventricular Ejection Fraction in Patients with Coronary Artery Disease QT c interval, QT dispersion, left ventricular systolic ejection time and left ventricular ejecti¬on fraction (EF) were assessed in 57 patients with coronary artery disease(CAD). 38 patients with left ventricular regional wall motion abnormality (groupl) had increased QTc interval and QT dispersion than 19patient with normal left ventricular wall motion (group2). left ventricular systolic ejection time were not different between group 1 and 2. Statistically significant correlati¬on was found between the QTc interval and EF. Statistically significant correlation was not fo¬und betiveen the QT dispersion and QTc interval. These results provide insight into the mecha¬nism of arrhythmias in patients with CAD.
