title: [Informative value of the indicators obtained during catheterization and ventriculography of the left heart ventricle].
abstract: It is found that the main indices determined in catheterization and ventriculography of the left ventricle still provide insufficient information. This is displayed by their considerable variations under normal conditions (conventional normal values). The functional left ventricular volumes vary least in adults; the ejection fraction is most informative. Contraction of the longitudinal axis of the left ventricle and of its transverse diameters and the circular rate of myocardial contraction are most variable. It is necessary to generalize a great scope of material to obtain the normal sex and age values of all indices.
