Abstract
A wavelet transform and pattern recognition method for analyzing a subject's heart sounds including (a) obtaining subject-related heart-sound data utilizing a first sampling rate, (b) obtaining simultaneously existing subject ECG data, including pre-selected ECG fiducial data, and (c) processing such obtained data including, relative to the heart-sound data, (1) computing the maximum-overlap discrete wavelet transform (MODWT) for a preselected number of wavelet scales, (2) locating the peaks in time of the absolute values of the MODWT coefficients respecting each of a such scales, and (3), for each such scale, (i) interpolating between the located peaks, and (ii) subsampling each interpolation result at a second sampling rate which no greater than the mentioned first sampling rate.
