Automated Detection and Removal of Pacing Artifacts from ECG Signal

Rajkumar Dhar, Shivangi Kewalramani, Larisa Tereshchenko

Pacing artifacts in electrocardiogram (ECG) signals can interfere with accurate waveform analysis, making their detection and removal essential for reliable interpretation. We present an algorithm and provide MATLAB code to detect and remove pacing …
