Key result
Sym4 wavelet and adaptive filtering greatly improve ECG signal-to-noise ratio over standard algorithms.
Why the study?
Increasing cardiovascular and related health risks necessitate ECG monitoring, prompting research to enhance ECG signal quality using wavelet transform and adaptive filters.
Answers are grounded in this paper and cite their sources.
Wavelet transform combined with adaptive filtering can significantly improve the signal-to-noise ratio of ECG recordings, enhancing the visibility of main signal features.
The increasing risk of cardiovascular diseases, stress, high blood pressure, obesity, sleep disorders, and depression causes electrocardiogram (ECG) monitors to be used for diagnosing health. The main objective of this research is to enhance the quality of the ECG signal using wavelet transform and adaptive filters. This research has been made as descriptive-analytic and the method is used in the signal processing stages to calculate the ECG modulation spectrum, the spectral-modulation filtering scheme, and the ECG database from the standard algorithm and performance criteria. The results of the simulation indicate that the conversion of Sym4 and the adaptive filter with the size of 0.0005 and the length of the filter of 25 signals to the noise will be greatly improved to reveal the main features of the ECG signal.

Hatamian et al. (2023) studied Cardiovascular diseases (ECG monitoring). Wavelet transform (Sym4) and adaptive filters was evaluated on Signal to noise ratio and ECG signal quality. The conversion of Sym4 and an adaptive filter with a size of 0.0005 and length of 25 greatly improved the signal-to-noise ratio to reveal the main features of the ECG signal.
