Original Abstract

The paper deals with a new method for detection of myocardial ischemia caused by acute coronary artery occlusion in early phases. The method is based on analysis of intra-QRS changes in time-frequency phase spectra generated by wavelet transform. To verify the method, 11 Langendorff-perfused rabbit hearts have been used. The presented results show that models can detect early ischemia in one of three orthogonal leads as early as one minute after coronary artery occlusion. Further, the method is compared to the traditional ST-segment analysis.
