[Study of left ventricular function. Part II: systolic perimetric variations (author's transl)].
New parameters for the study of ventricular dynamic, which analyze the perimetric dimensional variations of the ventricular margin on the cineventriculographic projective plain, were introduced. Three usable methods for these determinations are described: 1) the systolic dimensional variation of the total perimeter; 2) the contribution to the total perimetric length and the systolic shortening of the anterior and posterior wall; 3) the contribution of the telediastolic and the telesystolic length to the anterior or posterior wall and the systolic shortening (in mm/m2 of the corporeal surface and in the percentage of the respective telediastolic length) of each marginal region.
