title: [Diagnosis of combined myocardial ventricular hypertrophy using precordial mapping. II. Selection of the parameters of the cartogram of diagnostic significance for the differential diagnosis of combined myocardial hypertrophy and its isolated forms].
abstract: A new approach to the choice of diagnostic criteria of combined ventricular hypertrophy (CVN) is proposed: after determination of EKG parametres differing from the norm are separately compared to the EKG parametres in isolated left ventricular hypertrophy (LVH) and right ventricular hypertrophy (RVH). The diagnostic parametres were chosen on the basis of computer statistical analysis of EKG-35 data of 136 patients with CVH, 39 with LVH, 57 with RVH and 71 normal subjects. For differentiation from LVH the amplitude/area ratio (S10 + S17 + S24)/(S1 + S8 + S15) and R27/R17 was effectively used, for differentiation from RVH parametres R14/R1 or S25/S27 are recommended. The amplitude parameters provide the sensitivity of the method of 58.8% with the specificity of 94.6%; the use of area ratio of the same waves increases sensitivity up to 72.8% with the specificity of 94.4%. Sensitivity of the method with the use of the Sokolov-Lyon criteria for diagnosis of LVH and RVH in the same groups was 9.6% with the specificity of 94%.
