The detection method for atrial late potentials based on eigenspaces analysis of ecg wavelet pattern

We assume that mathematical orthogonal transformations can be applied to the problem of atrial late potentials (ALP) detection in the systems of highresolution electrocardiography. Specifically, we propose an integrated approach to identify the lowamplitude high-frequency part of ECG with ALP using the wavelet transform to further separate it into a diagnostically important signal and noise by decomposition in the basis of eigenvectors. Crucially, we demonstrate the results of the conducted model experiment aimed at the ALP detection by employing the proposed method in the MATLAB system.
