This paper presents a compressive sampling (CS) based measurement method for estimation of radial artery pulse wave from bio-impedance (Bio-Z) variation. The mathematical steps of the method, the 3D electrical model of the wrist used for simulations as well as the preliminary simulation investigations are presented. The reported result shows that the proposed method could be used to estimate radial artery pulse wave, which could be further used in blood pressure (BP) computation.

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.
