Apparatus and method for Ecg motion artifact removal

The present invention proposes a device for reducing motion artifacts in the patient's ECG signal. The apparatus includes a calculation unit for calculating a mean value beats from the ECG signal, a first acquisition unit for acquiring a residual signal based on the average value beats calculated from the ECG signal and the ECG signal a second acquisition for acquiring filtering unit and, ECG signal is modified based on the ECG signal and the mean value beats is the filtered perform the filtering of the residual signal using one or more cut-off frequency It has a unit, and a determination unit for determining the one or more cut-off frequency of the filter based on the acceleration signal representing the operating state of the patient. By using the proposed device, motion artifacts can be significantly removed from the ECG signal, the quality of the ECG signal, therefore, can be improved.
