Results of machine-made diagnoses of myocardial infarction based on orthogonal leads of the SVEC-III system, as modified by L.I. Titomir, are presented. In view of the fact that local changes in V3 lead are not always expressed in orthogonal leads there were constructed statistical algorythms of the myocardial infarction diagnosis according to X, Y, Z leads and from X, Y, Z, V3 and Y, Z, V3 leads. The algorythms are constructed on the ground of aposterioral probabilities calculated from the Baves formula. The diagnosis was established with reference to the QRS complex, which proved to be the most valuable diagnostic parameter.
