title: [Measurement of mean pulmonary pressures and right systolic ventricular pressure by radiocardiography].
abstract: Computer exploitation of some parameters of the radiocardiogram and of the pressures measured by catheterization in a series of 678 subjects, studied both in Paris and in Prague, has made it possible to establish regression equations providing the rates of mean pulmonary arterial and wedge pressures together with the systolic right ventricular pressure on the basis of the radiocardiogram data. The latter was obtained by the conventional technique of the isotope dilution curves or by gamma-angiocardiography. Easy repetition of radiocardiography makes it an interesting investigation for the haemodynamic follow-up of the patients with heart disease.
