目的:设计一个心电信号研究系统,该系统是远程心电监护仪器研制中的重要组成部分。方法:先用高性能的PC机和高性能的DA转换器搭建一个硬件平台,再以Visual C++6.0为平台,利用面向对象语言编程建立MIT-BIH心电数据库。结果:系统可以对MIT-BIH心电数据库中的心电和呼吸数据进行管理和回放,并建立实验数据平台,来产生模拟的心电、呼吸等生理信号,可用于研发远程心电监护仪器调试使用。结论:可为以后心电信号的研究分析和相关仪器的开发提供了一个优秀的研究平台。

Objective： In this paper, we design an electrocardiogram signal research system. This system is the important part of the remote electrocardiogram monitor instrument. Methods： First, to build a hardware platform with high-performance Personal Computer and high-performance digital-analog converter. Then use the object-oriented programming language to establish MIT-BIH electrocardio- gram database, which is based on the Visual C＋＋6.0 platform. Results： It can manage and replay the electrocardiogram and the respiration data in the MIT-BIH database. The established experimental data platform generates simulated electrocardiogram, respiration and other physiological signals, which can subsequently use the signal to debug the remote electrocardiogram monitoring instrument. Conclusion： It will finally use for the subsequent electrocardiogram analysis and development of instrumentation, which provides an excellent research platform.
