Multiwavelet-based ECG compressed sensing with samples difference thresholding

Abstract

This paper introduces a novel Multiwaveletbased hybrid method of Compressed sensing (CS).A case study of CS and reconstruction of Electro Cardio Diagram (ECG) signals with the presented method was performed. For ECG signals the proposed method does not require a wave position detector and can reconstruct the signal with minimal DC offset error. The method is completely patient-agnostic and does not require prior patient-specific information as well. The proposed method was evaluated using the MIT-BIT database. The obtained results show a good reconstruction quality while keeping a high compression ratio.
