Coronary heart disease (CHD) is the leading cause of mortality and morbidity worldwide affecting nearly 16 million persons over 20 years of age in the USA [1-4]. Ventricular arrhythmias are the more predominant cause of sudden cardiac death (SCD) in patients with coronary heart disease [5-7]. Several electrocardiographic indices have been proposed for risk stratification and prognosis in patients with coronary heart disease [8-10]. It is well known the association of prolonged QT interval and malignant ventricular arrhythmias and SCD. A prolonged QT interval has been shown to be closely associated with increased risk for SCD in some congenital and acquired channelopathies. Therefore, several studies have used the prolongation of QT interval as an index for predicting fatal arrhythmia and SCD in different entities [11-13]. In addition, another electrocardiographic interval, the interval from the peak of the T wave to the end the T wave, that is, the Tpeak-Tend (Tp-Te) interval has been proposed to be utilized in the prediction of malignant ventricular arrhythmias and SCD in some ion channel diseases [14-16].
