摘要：

目的研制一款面向家庭的心电监护系统。方法以基于ARM920T的s3c2440为核心，控制心电信号采集，并结合嵌入式软件技术，实时显示、分析和记录心电信号，对患者进行监护。算法部分采用适用于嵌入式系统的动态差分阈值法检测QRS波波群。结果该监护系统能实时、动态显示心电波形，并可以识别4种心率异常，能较好地反映和分析患者的心电活动状况。结论该心电监护系统操作简便，运行稳定，能够满足一般家庭需求，具有良好的应用前景。

Objective To develop an electrocardiograph(ECG) monitor for family health care. Methods The ARM920t-based microprocessor s3c2440 was adopted as MCU which controlled the ECG data acquisition. The ECG signal were recorded and displayed in real time based on the embedded software which was designed integratedly to analyze the abnormal ECG signals. In order to detect the QRS wave accurately, the difference and threshold methods, which were perfect for embeded system, were adopted. Results The system displayed the ECG waves dynamically in real time. It recognized four types of abnormal ECG signals and analyzed the status of the patient’s ECG signals well. Conclusions The ECG monitor works reliably and is easily operated, that satisfies the demand of family care, and has broad application prospects.
