title: [Dynamic radionuclide ventriculography in the diagnosis of heart and lung diseases].
abstract: The authors have provided a comparative analysis of various modifications of radionuclide ventriculography and assessment of their potentialities for clinical use. A total of 120 patients with chronic nonspecific lung diseases, coronary heart disease and rheumatic heart disease were examined. It was established that the most accurate information to assess myocardial contractility was obtained by a method of the determination of the ejection fraction by the "activity-time" curve with a fixed zone of interest, and the universal patient's position was the left front oblique projection. The right ventricular ejection fraction was determined in parallel with the study of the left ventricular ejection fraction characterizing myocardial contractility in cardiovascular pathology. The study of the former extended significantly the potentialities of radionuclide ventriculography, allowed the assessment of the hemodynamic state of the lesser circulation and compensatory potentialities of the right ventricle of the heart in cardiopulmonary pathology.
