本文简要介绍了体表心电电位图的发展历史及现状。体表心电电位的研究目前主要集中于两个方向 :采集系统和数据处理方法。对于采集系统 ,本文着重介绍了利用虚拟仪器概念和高速开放总线标准的设计方案 ,而对于心电数据处理方法则分别从定性和定量的方面给予介绍。其中在定性方法中介绍了静态和动态标测法 ,在定量方法中则介绍了统计学方法、逆运算方法和主分量分析方法 This article briefly introduced the history and status quo of the development of body surface electrocardiogram. The study of body surface ECG mainly focuses on two aspects at present: acquisition system and data processing method. For the acquisition system, this article focuses on the use of virtual instrument concepts and high-speed open bus standard design, and for the ECG data processing methods were given qualitative and quantitative aspects are given. Among them, static and dynamic mapping methods are introduced in the qualitative methods, and statistical methods, inverse methods and principal component analysis methods are introduced in the quantitative methods
