摘　　要：窦性心律合并房性并行心律及频发室早的动态心电图相对复杂,要想准确快速地分析几乎是不可能的,除非借助于心电散点图。时间散点图能显示心律失常发生的时刻及持续时间;Lorenz散点图可反映主导心律与辅加心律各自的电生理特征;差值散点图则能清楚地揭示出Lorenz散点图上重叠难辨的节律信息。这三种散点图相互补充、互为印证,全方位、多角度地刻画了窦性心律合并房性并行心律及频发室早的竞争与干扰过程。掌握心电散点图这种简洁而高效的分析工具和语言,不仅有助于准确快速分析动态心电图,也为深入了解心律失常的电生理意义打开了一扇窗口。The ambulatory electrocardiography（AECG） of sinus rhythm complicating atrial para- systolic rhythm and frequent premature ventricular contraction is relatively complex. It is almost im- possible to analyze it accurately and quickly without the help of ECG scatterplot. The t-RR scatterp｜ot can show the occurring time and duration of arrhythmia; Lorenz scatterplot can reflect electrophysio- logical characteristics of dominant rhythm and auxiliary rhythm respectively; difference scatterplot can clearly reveal the overlapping and illegible rhythm information in Lorenz scatterplot. The three kinds of scatterplots make complementation and confirmation mutually, depicting the competition and interfering process of sinus rhythm complicating atrial parasystolic rhythm and frequent prema- ture ventricular contraction by muhiple perspectives. It is helpful to analyze AECG accurately and quickly, and comprehend the electrophysiological significance of arrhythmia further, if clinicians can master the simple and effective analysis method of ECG scatterplot.
