R APPARATUS AND METHOD FOR DETECTING R PEAK OF ECG SIGNAL USING ADAPTIVE MEDIAN FILTER

摘要

A method for detecting an R peak of an electrocardiogram signal using an adaptive median filter is provided. The method may include passing an ECG signal (hereinafter referred to as a first ECG signal) received from an ECG signal measuring device having a predetermined sampling rate through an adaptive median filter; calculating a difference between the first ECG signal and a signal passed through the adaptive median filter (hereinafter referred to as a second ECG signal); extracting an R peak candidate group by applying a maximum filter size and an adaptive threshold value applicable to the adaptive median filter to the calculated difference between the first and second ECG signals; and detecting an R peak candidate group having a maximum value among the R peak candidate groups as an R peak.
