摘　　要：长周期的出现使原有的心律失常散点图复杂化,而散点漂移法是破解此类病例的"秘密武器"。长周期相关的特征点集与无长周期的同名特征点集有相似性,相当于由后者"漂移"而来。Lorenz散点图的漂移规律:前周期延长向右移,后周期延长向上移,前后均延长右上移。差值散点图的漂移规律:前周期延长向左移,后周期延长向上移,中间周期延长右下移。本文以二度房室阻滞散点图为例,总结长周期相关点集与基础点集的位置关系,推广到早搏相关的特征点集,旨在通过探讨长周期心电散点图的解析技巧,为快速分析动态心电图奠定基础。The appearance of long period complicates the original scatter plot of arrhythmia,and the scatter point drifting method serves as a"secret weapon"to solve these cases.The long period related characteristic point set is similar to the homonymous one without long period,and the former is equivalent to a drift from the latter.The drifting law of Lorenz scatter plot is as follows:the extended front period moves to the right,the extended back period moves up,and both of the front and back period extend to the upper right.The drifting law of the difference scatter plot is as follows:the extended front period moves to the left,the extended back period moves up,and the extended middle period moves to the bottom right.Taking second degree atrioventricular block scatter plot as an example,this paper summarizes the positional relationship between long period related point set and basic point set,which is popularized to premature beat related characteristic point set.This paper aims to lay a foundation for rapid analysis of ambulatory electrocardiography by exploring the analytical skills of long period related ECG scatter plot.
