摘　　要：目的:将临床应用的体表心电图(ECG)和心外膜心电图同步采样,并将数据传送给上位机进行数据处理和图形分析打印,为临床心外科手术心电图监测和心血管药理动物实验提供新的采集分析系统。方法:本文从软、硬件上介绍了一种以微机为上位机的体表心电图和心外膜心电图同步数据采集系统的设计。结果:利用本文设计的体表心电图和心外膜心电图同步数据采集系统采集的数据准确,波形清晰。Objective： This article afforded a sampling and analyzing system for the ECG monitor in heart surgery and animal experiment in the cordis pharmacology in the clinic, synchronous sampling ECG and pericardial ECG in the clinic .Transmitting data under the control of a computer for data processed and graph analyzed and printed. Methods： The article introduced the design and parametric debug of a synchronous sampling system of ECG and pericardial ECG from two sides of hardware and software. Results： The data sampled by the system synchronous sampling ECG and pericardial ECG were nicety and the wave and graph were in focus.
