Key result
Combined mathematical morphological and wavelet filtering improves artificial ECG baseline wander suppression without waveform distortion.
Why the study?
Existing methods for suppressing baseline wander in ECG signals, such as wavelet-based and mathematical morphological filtering algorithms, introduce waveform distortions that degrade signal quality.
Population

A novel combined morphological and wavelet transformation filtering method improves ECG baseline wander suppression while minimizing waveform distortions.
Wan et al. (2019) studied Electrocardiogram baseline wander. Combination of mathematical morphological filtering (MMF) and wavelet-based (WT) algorithms vs. Other state-of-the-art methods (WT and MMF alone) was evaluated on Baseline wander suppression and waveform distortion avoidance. A combined mathematical morphological and wavelet transformation filtering method improved baseline wander suppression in artificial ECG signals while avoiding waveform distortions.
