摘　　要：针对目前心电信号研究缺少临床试验数据的情况,本文提出了使用国际公认的可作为标准的心电数据库作为心电算法的输入,并为心电监护类系统和便携式心电监护仪等提供测试信号源。本文采用跨平台的C++应用程序开发框架Qt来实现系统,本系统不仅应用于PC机,还可应用于便携式心电监护仪,识读的心电信号经过D/A转换,模拟实际临床采集到的信号,提供给心电监护系统进行仿真实验。At present, because of the lack of clinical trial data in the study of ECG signal,this paper proposed to use the internationally recognized standard ECG database as the input of the algorithm, and provide the test signal source for ECG monitoring system and portable ECG monitor etc.. In this paper Qt as the C＋＋ application development framework of cross platform is used to realize the system, this system can be not only applied to the PC machine, also used in portable ECG monitor, convert the reading ECG signal through D/A, analog the actual clinical collected signals, and applied to the ECG monitoring system in simulation experiment.
