98 patients with isolated rheumatic mitral valve defects of the heart entered the study. Their central hemodynamics was studied intraoperatively before surgical correction of the defect. The results were compared to those provided by conventional noninvasive methods: chest x-ray, ECG, echo-CG, external respiration function test. Correlation analysis using computer intellect PolyAnalyst v.1.01R helped to design a program and practical nomogram which can quantitatively determine the degree of pulmonary hypertension on the basis of digital values of Rv1 wave amplitude (ECG) and right ventricular cavity size (echoCG).
