An ECG acquisition and analysis system which can work in motion state of human body. A highly integrated single-lead ECG front-end is used for hardware filtering and amplify ECG signal. Wavelet threshold is used to reduce noise in ECG. Using human body motion acceleration sensor to obtain information of body motion and adaptive filtering is carried out on ECG and eliminate motion artifact in ECG. Data is transmitted from terminal to mobile phone through Bluetooth and user can measure ECG anytime and anywhere. The results show that the system can effectively eliminate motion artifact according to body motion and maintain ECG waveform

the system can meet conventional mobile ECG monitoring applications.
