当房室交接区发生二度及以上房室传导阻滞时，间歇或连续出现的 RR 长间歇总是被结性逸搏或结性逸搏心律所消除。这其实是人体的一种自我保护机制。结性逸搏或结性逸搏心律的出现，使原本相对复杂的二度房室传导阻滞心电图更加复杂，而24 h 动态心电图更是囊括了长短周期的各种可能组合。然而，分析软件中的心电散点图则从不同角度，一目了然地显示了结性逸搏与结性逸搏心律的两个显著电生理特征，即逸搏周期相对固定和逸搏心律随时重整。本文结合实际病例，总结了逸搏心律的三种散点图特征及其分析方法。特征性的心电散点图为临床上快速准确识别结性逸搏与结性逸搏心律提供了可能。

At the occurrence of second degree (or higher) atrioventricular block in the atrioventricular junctional area,RR long interval which appears intermittently or continuously was usually eliminated by nodal es-cape or nodal escape rhythm.It is actually a kind of self-protection mechanism of human beings.The appearance of nodal escape or nodal escape rhythm complicates the ECG of second degree atrioventricular block which is originally relatively complex while 24-hour ambulatory electrocardiography includes all possible combinations of various long and short cycles.However,ECG scatterplot in analysis software clearly manifests two significant electrophysiologi-cal characteristics of nodal escape and nodal escape rhythm from different angles,that is,escape cycle is relatively fixed and escape rhythm readjusts at any time.This paper summarizes three scatterplot features of escape rhythm and its analysis method,based on explanation of practical cases.Characteristic ECG scatterplot makes it possible to recognize nodal escape and nodal escape rhythm quickly and accurately.
