Abstract：Heart system disease prevention and diagnosis has become the top issue in medical field.
Dynamic electrocardiography (ECG) signal monitor was the main mean to solve this problem. On the
basis of ECG signal analysis theory, this paper introduced the hardware components of the dynamic ECG
monitoring system, investigated the status of ECG electrodes and hardware circuit at home and abroad. In
the algorithm aspects, it also elaborated QRS wave automatic detection technology. The paper illustrated
the filter technology of motion artifact interference, studied the related research results of QRS potter
character extraction. Finally, it compared different quality evaluation method based on ECG signal data
and ECG signal characteristic parameters, illustrated different cases of ECG signal quality evaluation.
