Objective
Abnormal ventricular repolarization, particularly in structural and arrhythmic heart diseases, is the marker of arrhythmogenesis and cardiovascular mortality and morbidity. Tpeak-end interval shows left ventricular transmural dispersion of repolarization and the electrocardiographic index Tpeak-end/QT rate shows ventricular arrhythmogenesis. Increase in both parameters show significant increase in major arrhythmogenic events in patients undergoing cardiac resynchronization, Brugada syndrome and nonischemic cardiomyopathies. In cases except this group of patients, it is accepted that the prognosis of idiopathic monomorphic ventricular premature beat is acceptable. The aim of our study is to determine the relationship between Tpeak-end/QT index and Tpeak-end interval with ventricular extrasystoles (idiopathic ventricular premature beat) in patients with preserved left ventricular function.
Materials-Methods
32 patients with (group 1) and 31 patients without (Group 2) at least 1000 idiopathic ventricular premature beats in 24-hour rhythm holter recording were included in the study. The mean age of patients was 51,2 ± 16,3. Patient demographic characteristics, transthoracic echocardiography and rhythm holter data have been evaluated. Tpeak-end interval and Tpeak-end interval to QT interval ratio of patients have been calculated.
