体表电位图的测量与处理系统

本文叙述了一台以Intel 8086CPU为核心的微机处理系统,用以测量体表电位图。该系统具有64个模拟输入通道,采集人体胸廓表面的各点心电信号,经放大、A/D特换后送入微机系统,用插值法计算并在监示器上显示任意点的心电图和任一时刻約体表电位图。文末给出两名正常人的心电体表电位图。

A MEASURING AND PROCESSING SYSTEM FOR THE BODY SURFACE POTENTIAL MAP

A microcomputer processing system with Intel 8086 CPU has been descri bed in this paper. The system may be reliably used in the measurement of the body surface potential map. It has 64 analogue input channels for detecting electrocardiography (ECG) signals at various points on the chest surface. After being amplified and A/D Converted, the data must be transferred to the microcomputer system for processing with the help of the interpolation method. The ECG at any point and the body surface potential map in any moment can be displayed on the monitor screen. The paper, in its last part, also presents the results of the body surface potential map obtained from two healthy persons.
