摘　　要：为获得大量的原始人体心电数据,研制了一款三导联心电采集系统。本系统主要由MSP430单片机开发而成,可以连续采集,经差分放大、功率放大,最后经A/D后存储在芯片内的flash中,并可通过LabVIEW编译的软件控制串口将数据传到计算机中进行后期的数据分析。经测试证实系统安全、稳定性好,可用于心电数据的采集和分析。A three lead ECG acquisition system was developed in order to acquire large number of ECG. The system was developed based on MSP430. It could acquire data continuously and had the functions of amplifying signals, storing data in flash after A/D and receiving data through COM with the software programmed with LabVIEW. It was proved that the system was safe and stable for testing ,and it could be used in ECG data acquision and analysis.
