Key result
Contemporary signal processing techniques such as discrete wavelet transform, empirical mode decomposition, variational mode decomposition, and empirical wavelet transform are reviewed for ECG denoising.
Why the study?
Artefacts and measurement noise often impede accurate ECG feature extraction, necessitating noise-free signals for improved cardiac analysis and interpretation.
This review summarizes contemporary signal processing techniques for ECG denoising and feature extraction, which are essential for accurate cardiac signal analysis.
ECG artefact removal methods lack standardization; leaves open rigorous validation trials before clinical adoption.
The electrocardiogram (ECG) is a non-invasive approach for the recording of bioelectric signals generated by the heart which is used for the examination of the electro physical state, the function of the heart, and many cardiac diseases. However, various artefacts and measurement noise usually hinder providing accurate feature extraction such as power line interference, baseline wander, electromyographic noise (EMG) and electrode motion artefact. Therefore, for better analysis and interpretation ECG signals must be noise-free. Most recent and efficient techniques for ECG denoising and feature extraction techniques have been reviewed in this paper, as feature extraction and denoising of ECG are remarkably helpful in cardiology. This paper presents the review of contemporary signal processing techniques such as discrete wavelet transform (DWT), Empirical mode decomposition (EMD), Variational mode decomposition (VMD) and Empirical wavelet transform (EWT) for ECG signal denoising and feature extraction.

Mir et al. (2021) conducted a review in Cardiac diseases (ECG signal processing). ECG denoising and feature extraction techniques (DWT, EMD, VMD, EWT) was evaluated. Contemporary signal processing techniques such as discrete wavelet transform, empirical mode decomposition, variational mode decomposition, and empirical wavelet transform are reviewed for ECG denoising.
