Power Line Interference and Baseline Removal in ECG

Authors: Sai Venkatesh Balasubramanian

Power Line Interference, typically occurring at 50-60Hz frequencies and baseline drift at sub-Hertz ranges are two of the key sources of corruption of ECG signals. In this short article, elimination/mitigation of these effects using notch and high pass filters termed DC notch filters are discussed. The results plotted highlight effective removal of PLI and baseline effects.
