针对家庭实时监测心电和呼吸的需求，本文设计了一款基于Android智能手机的便携式心电与呼吸监测系统。系统通过心电电极采集心电和呼吸信号，经蓝牙将采集的信号传输至Android智能手机端进行实时分析、显示和报警。对采集的心电信号进行预处理，用差分阈值法和局域变换法检测QRS波群，并判断是否有心电异常，同时根据呼吸信号计算出呼吸频率并监测呼吸暂停状况。模拟和真人测试表明，本系统能够准确地计算心率、呼吸频率、监测心电异常状况。

In order to monitor the heart and respiration situation in real time, this paper designs a portable system based on Android platform to monitor ECG and respiration signals. The ECG and respiration signals are detected through ECG electrodes. Then the signals are transported into the Android device via Bluetooth for further analysis and display. In the Android device, the collected ECG signals are preprocessed and the QRS complexes are detected with both difference threshold method and local transform method. Then the ECG abnormality may be determined when it happens. At the same time, the respiratory rate is calculated and the apnea condition may be detected. Simulation and real test show that the system can accurately calculate the parameters related to the heart and respiration of human body, and give an effective and reliable monitor for the abnormal on heart and respiration.
