摘　　要：心电图机和心电监护仪在心血管疾病的诊断中发挥着重要的作用,仪器检测结果的准确性对患者的安全治疗有着重大的影响。该研究设计了一种新型的心电信号发生器,用于检测心电图机和心电监护仪的心电信号是否异常,其以AT89S51为主控芯片,以标准心电信号为基准信号,经数模转换后,再通过心电导联线触发心电图机和心电监护仪的心电模块实现检测,通过检测结果,设备科工程师可以比较准确及时地了解设备的输出情况,利于提高医疗质量,降低医疗风险。Both electrocardiographs and electrocardiograph monitors play an important role in the diagnosis of cardiovascular diseases.Whether they can accurately detect the electrocardiogram(ECG)of patients has a significant impact on the safe treatment.In this study,a new type of electrocardiosignals generator was designed to detect whether the electrocardiosignals of electrocardiographs and electrocardiograph monitors were abnormal.The AT89S51 singlechip was selected as the main control chip,and the standard electrocardiosignals were defined as the reference signals.After digital-to-analog conversion,the ECG modules of the ECG recorders and ECG monitors could be triggered by the electrocardiographs and the electrocardiograph monitors through the ECG leadwires to detect signals.Through the detected results,the engineers of the equipment department could understand the output of this kind of devices accurately and timely,which was he lpful to improve medical quality and reduce medical risks.
