摘要：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.
