    Abstract:
    On the basis of verified material (136 patients with combined myocardial hypertrophy--CMH, 39 with left ventricular hyperthrophy, 57 with right ventricular hyperthrophy and 71 normal subjects) a principally new approach to computerized quantitative analysis of the EKG data has been worked out. Results of study of the informative value of 35 praecordial EKG in the diagnosis of CMH are presented. The authors propose to use the amplitude and area of S and R waves as well as their sum calculated with the use of non-traditional leads. This method makes it possible, when CMH differs from the norm, to increase the sensitivity of the electrocardiography up to 86.8% and its specificity up to 91.5%, which is more effective than the traditional Sokolov-Lyon criteria (sensitivity of 64% and specificity of 87.3%). Nevertheless, these characteristics are ineffective in differential diagnosis because increase in these values can be observed also by isolated hyperthrophy.
