Abstract：Objective： To design an ECG Monitoring System based on the Android platform, the data is sent to the phone, and displays the ECG waveform and heart rate. Methods： Based on the Android platform, combined the Freescale microcontroller 9SXS128 and Bluetooth module designed an ECG Monitoring System based on Android platform, gathers and amplifies the ECG signals, eliminates noises, converts to digital signals and then sends by bluetooth.The system consists of power supply module, ECG acquisition hardware module, the data sampling microcontroller, Bluetooth transmitter module and an Android phone software several major components. Results： First of all, Obtained Ecg signal from the limb lead, by the MCU AD, the data is sent to the phone by serial to Bluetooth interface, and displays the ECG waveform and heart rate. Conclusions： We de- signed and completed the hardware circuit board and software programs of ECG acquisition module. Programmed ECG moni- toting applications which based on a android mobile phone. System obtaining ECG signals by limb leads and eventually displayed in real time on the phone, The system has features of small volume, low power consumption and simple operation. After debugging, the system is stable, the Ecg signal can be displayed in real time in the mobile phone interface, accurate heart rate measurement. With this design effectively alleviate the difficult problem of medical treatment, has a great prospect in the national circumstances of the relative concentration of medical resources, android mobile phone-based health surveillance.
