Tp-Te间期可看成是过去QT间期离散度演变而来的新概念。[定义]Tp-Te间期是指体表心电图T波顶点到T波终末点间的间期(图1A)。[测量方法]测量方法有手工和计算机两种测量方法。测量值的准确度取决于T波顶点和终点的认定,计算机自动测量值相对稳定、可靠。[Tp-Te间期正常值]一个是Tp-Te间期正常值为80~100ms,>100ms为延长,另一个值为Tp-Te间
The Tp-Te interval can be regarded as a new concept evolved from the dispersion of the QT interval in the past. [Definition] Tp-Te interval refers to the interval between the T-wave peak of the body surface electrocardiogram and the terminal end of the T wave (Fig. 1A). [Measurement methods] Measurement methods are manual and computer two kinds of measurement methods. The accuracy of the measured value depends on the identification of the T-wave apex and end point. The automatic measurement value of the computer is relatively stable and reliable. [Normal Tp-Te Interval] One is the normal Tp-Te interval of 80-100 ms,> 100 ms is extended, and the other is Tp-Te
