摘　　要：针对目前传统心电图机的主要缺陷,基于LabView虚拟仪器开发平台实现了一种新型的心电信号虚拟仪器;该系统导入心电信号,经放大滤波电路处理后由GPIB数据采集卡输入计算机,再在虚拟仪器软件上进行分析显示结果;应用结果表明,该系统结果准确、容易实施、造价低廉。The design and implementation of virtual electrocardiogram testing instrument is introduced. The instrument consists of three parts： amplifying and filtering circuit, GPIB card and virtual instrument software. The circuit is designed by taking INA128P IC as its core. The card is used for data grabbing. The software is developed using LabView. While the instrument is working, ECG signals are amplified and filtered by the circuit, ducted into computer through GPIB card, displayed on the virtual instrument software developed by LabView.
