摘要: Tp-e间期是指心电图T波顶点到T波终点之间的时间间期，是QT间期的终末组成部分，能够代表在绝大部分心室肌复极后小部分心室肌间复极的离散度，Tp-e/QT比值指Tp-e间期与QT间期的比值，是比Tp-e更敏感的预测心律失常的指标，因为其可以不受心率变异和QT间期个体间波动影响，是心源性猝死的可能性重要预警。现对其研究予以综述，望对临床中恶性心律失常等的发生提供预测价值。
Abstract: Tp-e interval refers to the time interval between the T wave apex and T wave endpoint of electro-cardiogram, which is the final component of QT interval and can represent the dispersion of re-polarization between a small part of ventricular muscles after repolarization of most ventricular muscles. Tp-e/QT ratio refers to the ratio of Tp-e interval to QT interval. Tp-e is a more sensitive predictor of arrhythmia than TP-E because it is independent of heart rate variability and QT inter-individual fluctuations, and is an important predictor of sudden cardiac death. This paper reviews its research and hopes to provide predictive value for the occurrence of malignant arrhythmia in clinic.
