The analysis method of acoustocardiogram for detection of cardiovascular diseases at use of continuous wavelet transform is developed. The mathematical model of a cardiosignal is offered. The comparative analysis of wavelet-spectrums of cardiosignals for different states of cardiovascular system is realized: at the normal sinus rhythm and at the sinus tachycardia. The measure of distinguishability with respect to detection of cardiovascular system diseases is developed.
