ABSTRACT
In 32 patients with rheumatic mitral stenosis a set of quantitative rheographic pulmonary data was compared with the values of pulmonary artery pressure obtained by way of pulmonary artery catheterization. The diagnostic value of the mean rate of slow filling (Vm.s) and of the Q--a interval was shown for the diagnosis of pulmonary hypertension, their introduction into everyday practice was substantiated. Appropriate regression equations for Vm.s and mean pulmonary artery pressure were compiled: y equals 83.7--94.x, and for the Q--a interval: y equals 4.46.281 300x. In mitral stenosis cases a reduction of the rheographic systolic index was established, as well as of the amplitude-frequency index and of the maximum rate of fast filling.
