[Normal values of left ventricular function. Biplanar angiocardiography with reference to sex-specific differences]. / Normalwerte der linksventrikulären Funktion. Biplane Angiokardiographie, unter Berücksichtigung geschlechtsspezifischer Unterschiede.

Normal values of left ventricular function have been determined in 24 patients by means of biplane angiocardiography. Global parameters were chamber volume, ejection fraction and muscle mass. Regional ventricular function was determined by means of an orthogonal and radial axial system. Radial axis shortening parameters showed smaller standard deviations and smaller coefficient of variations than orthogonal parameters. The smallest coefficient of variation elicited regional area reduction methods. Women showed significantly lower chamber volumes and muscle mass than men. There was no difference between the two sexes in the ejection fraction and wall thickness.
