Abstract

Motion artifact, caused by skin stretch near an electrode is a significant source of noise in ECG recording, particularly during ambulatory recordings and stress tests. With recessed Ag-AgCl electrodes, motion artifact results, primarily, from potentials generated by skin stretch at the electrode site. The authors have investigated adaptive removal of motion artifact using a skin stretch signal derived from sensors mounted on a foam electrode. Preliminary results indicate that adaptive removal of motion artifact can reduce motion artifact by as much as 12.5 dB
