Abstract: In traditional electrocardiogram (ECG) measurement,patient with limited activity and uncomfortable wearing is still a practical problem.The paper proposed a wearable ECG acquisition and analysis system based on the features of wearable computing.The system samples ECG signals by own designed Synchrony 12/single lead ECG acquisition device.ECG data can be saved on the device or be transmitted to server by 3G network.And ECG data can be analyzed by own designed software which can provide auxiliary information on clinical heart diagnosis,and perform ECG monitoring.Furthermore,after carefully studying interposer electrode and fabric electrode,the paper proposed a strategy to combine interposer and fabric electrode together.This was done to improve the quality of ECG signal. The experiment data of wearing the ECG acquisition device with interposer fabric electrode show that the ECG measurement procedure is comfortable,and the ECG signal quality can reach the requirement of clinical ECG monitoring.
