摘　　要：目的 :设计一种基于Andriod平台的心电监护、无线传输与手机显示系统,可用于家庭或社区范围内的心电监测。方法:首先通过心电采集模块提取被监测者的心电信号,然后利用MSP430F149单片机进行A/D转换并将转换后的数据文件适当处理后经串口发送至蓝牙模块,再无线传输至智能手机,存储在手机的安全数码卡(secure digital memory card,SD)上。智能手机端通过设计蓝牙的应用程序编程接口(application programming interface,API)开发类实现与下位机通信,可打开已存储的心电数据文件并绘制成心电波形图,观察心电图是否有明显异常。结果:该系统能正常采集到人体心电信号并无线传输至手机进行显示,无线传输距离为10 m。结论:该系统的设计有利于家庭其他成员或监护人员及时了解患者的心电状况,以实现对家庭患者的健康监护。Objective To design an ECG monitoring, wireless transmission and display system based on Android platform which could be used in the family or community for ECG monitoring. Methods The ECG signals obtained with acquisition module underwent A/D conversion with MSP430F149 SCM, and sent to Bluetooth module via a serial port after treatment,and then stored in the secure digital memory card（SD） of the smart cell phone. The communication was realized between the cell phone and the lower computer through application programming interface（API）, then ECG waveform could be formed based on stored ECG data to determine the presence of ECG. Results The system could realize ECG collection,wireless transmission and waveform display, with the wireless transmission distance being 10 meters. Conclusion The system facilitates ECG monitoring for patient care at home.
