Abstract
A method for ECG denoising based on wavelet shrinkage approach has been investigated. We have proposed a shrinkage threshold which is high for the non-informative wavelet coefficients and low for the informative coefficients. We have set up limitations for the difference between the thresholds of every two adjacent coefficients throughout the scales in order to avoid Gibbs effects.
