摘　　要：探讨散点漂移法在快速分析房性并行心律合并房性早搏(简称房早)未下传中的应用价值,为快速分析相关动态心电图奠定基础。选择房性并行心律合并频发房早未下传的典型病例以及房性并行心律合并成对房早单个下传等心律失常病例,结合散点漂移法分析其心电散点图特征,总结分析技巧。房早未下传所致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,特征点集向右移;后周期延长,特征点集向上移;前后均延长,特征点集右上移。差值散点图的漂移规律:前周期延长,特征点集向左移;后周期延长,特征点集向上移;中间周期延长,特征点集右下移。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”。This paper investigates the application value of scatter point drifting method in the rapid analysis of atrial pararrhythmia without atrial premature beats(APB)being conducted down,and establishes a foundation for rapidly analyzing related ambulatory electrocardiography.We selected typical cases of atrial pararrhythmia without frequent APB being conducted down,and arhythmia cases including atrial pararrhythmia complicated by paired APB individually conducted down.The characteristics of their ECG scatter plots were analyzed combined with the scatter point drifting method,and the analysis skills were summarized.There is an analogy between the characteristic point set related to long period due to unconducted down APB and the homonymous one without long period.The former is equivalent to a drift from the latter.The drifting law of Lorenz scatter plot is as follows:with extended front periods,the characteristic point set moves to the right;with extended back periods,the characteristic point set moves upwards;with extended front and back periods,the characteristic point set moves to the upper right.The drifting law of the difference scatter plot is as follows:with extended front periods,the characteristic point set moves to the left;with extended back periods,the characteristic point set moves upwards;with extended middle periods,the characteristic point set moves to the bottom right.The appearance of long period complicates the original scatter plot of arrhythmia,and the scatter point drifting method serves as a“secret weapon”to analyze these cases.
