The possibility of a theory tools application of signals identification measurements for the preliminary diagnosis of a human's large-focal myocardial infarction is described. The analysis of the electrocardiological signals is used for this purpose. In particular, the dependence of a cardiovascular system condition on the offered integrated interaction factors is established. The size of the integrated interaction factor is determined allowing predicting the existence of separate groups of a myocardial infarction. The possibility of this technique application for a preliminary diagnostics of a human's cardiovascular system condition is offered.
