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 D2jf, 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
