【摘要】 心脏是人体的重要器官,存在特殊的电生理机制,可呈现出多种形式的心电图。目前,临床对于心脏电生理现象的监测方法呈多样化,其中Lorenz散点图是近年研究热度较高的一种检查方法。Lorenz散点图是以大量连续心电波为数据,在二维坐标系中将连续的RR间期序列转化成的一张散点图形,能够直观、准确地从整体角度观察全部心搏信息,从而获取常规动态心电图分析方法无法观察的信息。本文就Lorenz散点图在心血管疾病中的应用进行综述,并指出其在心房颤动、心房扑动、并行心律、期前收缩等心律失常鉴别中具有明显优势。更多还原

【Abstract】 Heart is one of the important organs of human body,which has special electrophysiological mechanism and can present various forms of electrocardiograms.At present,there are various monitoring methods for cardiac electrophysiological phenomena,among which Lorenz scatter plot is one of the most popular methods in recent years.Lorenz scatter plot is a scattergram which is based on a large number of continuous ECG data.In two-dimensional coordinate system,the continuous RR interval sequence is transformed into a scattergram.It can directly and accurately observe all the heart beat information from the overall point of view,so as to obtain the information that can not be observed by the conventional dynamic ECG analysis method.This paper reviewed the application of Lorenz scatter plot in cardiovascular disease,and pointed out that it had obvious advantages in distinguishing arrhythmia such as atrial flutter,atrial fibrillation,parallel heart rhythm and premature systole.更多还原
