Abstract:

ECG signal detection is an important auxiliary means of doctor diagnosis treatment of cardiovascular disease,but due to the fact that ECG signal detection actual conditions are not ideal,ECG signal is often mixed with various kinds of interference signals,among which are EMG noise,the baseline drift and power-line interference.In this paper,the digital filtering method is used to eliminate the noises in ECG signals.The design of ECG signal filter improves both denoising effect and efficiency.
