Multiresolution wavelet analysis of ECG during ischemia and reperfusion

Abstract

ECGs from ischemic animals were analysed using multiresolution wavelets of G.S. Mallat (IEEE Trans. Pattern Anal., Machine Intell., vol. 11, no. 7, p. 674-93, 1989). The authors propose a new way, based on the detail signals D/sub 2j/f, for detecting injury related changes in the ECG. Analyses of experimental data reveal a short-term increase of magnitude in scales corresponding to the medium frequency components during occlusion of coronary vessels.<>
