METHOD OF ELIMINATING NOISE FROM ELECTROCARDIOGRAPHY SIGNAL AND ELECTROCARDIOGRAPHY SIGNAL SENSING APPARATUS THEREOF

摘要

A method of eliminating noise from an electrocardiography (ECG) signal and an ECG signal sensing apparatus thereof are provided. The method of eliminating noise from the ECG signal includes the following steps. The ECG signal is generated, and a median filtering process is performed on the ECG signal to obtain a median ECG signal. A calculation process is performed on the ECG signal and the median ECG signal, so as to obtain a detrended ECG signal.
