Abstract:

In order to solve the problems existed in Holter devices,such as traditional adhesive ECG（Electrocardiogram） electrodes irritate skin,signal to noise ratio degrade over time and the lack of ability of dynamic analysis,a wearable ECG monitoring system has been developed.A wearable shirt with embedded electrodes made by conductive fabric is produced and an ECG sampling device has been created.An abnormal ECG waveform detection algorithm based on R-R interval and QRS complex waveform analysis is designed and implemented as a software package on PDA（Personal Digital Assistant）.The effectiveness and reliability of the system has been verified through clinical testing.
