Abstract
Tp-Te interval refers to the duration from the peak to the end time points of T wave in electrocardiogram. Tp-Te interval is an electrocardiogram index reflecting mail-gnant ventricular arrhythmia, while Tp-Te interval mainly reflects ventricular transmural repolarization dispersion. The increase of ventricular transmural repolarization dispersion makes it easy to appear depolarization after repolarization, and forms functional conduction block between different regions, which leads to malignant arrhythmias. In this review we discuss how these markers have demonstrated to be effective to predict malignant arr- hythmias in medical conditions such as long and short QT syndromes, Brugada syndrome and so on. However, the same results have not been found in all conditions. Further studies are needed to reach a global consensus in order to incorporate these VR parameters in risk stratification of these patients.
