摘　　要：本文介绍了一种基于虚拟仪器的12导同步心电信号采集系统的研制方法。硬件由笔记本电脑、同步心电放大器、12位数据采集卡组成,程序用虚拟仪器编程语言LabWindows/CVI编写,界面模拟实际的采样仪器,可以设置采样参数、登记病例信息、采集时实时显示心电波形并将数据存盘。应用此系统,采集正常30例、异常150例心电数据存入心电数据库,效果良好。A 12-lead synchronous ECG signal acquisition system based on virtual instrument is presented. The hardware consists of a portable computer, an ECG signals amplifier, a 12-byte DAQ card. The software, written by LabWindows/CVI, has a virtual interface of real sampling instrument. Through the system, acquisition parameters can be set, the information of subject can be registered, real-time acquisition, display and save of data can be realized. The system works effectively and 30 normal and 150 abnormal ECG data was sampled and saved in the ECG dataset.
