Information flow of the study with three stages. The first stage is signal processing, which formed semi-synthetic data by superimposing a normalized raw ECG signal with an artificial baseline wander (BW or trend). The second stage is wavelet transform (WT) and BW removal. The third stage is WT evaluation, which measured the mean square errors between the normalized raw ECG data and the de-trended semi-synthetic ECG signal
