- Abstract
- Provided is a method of detecting the R peak of an electrocardiogram (ECG) signal using an adaptive median filter. The method includes allowing an ECG signal (hereinafter, referred to as a first ECG signal) received from an ECG signal measuring apparatus having a predetermined sampling rate to pass through an adaptive median filter, calculating a difference value between the first ECG signal and a signal (hereinafter, referred to as a second ECG signal) passing through the adaptive median filter, extracting R peak candidate groups by applying a maximum filtering size and an adaptive threshold applicable in the adaptive median filter to the calculated difference value 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.
