[Mechanical tension in different parts of the left ventricle of the heart exposed to inotropic factors]. 1985

A M Chernysh, and V Ia Tabak, and M S Bogushevich

A study was made of the effects of different inotropic factors on mechanical tension in the left ventricular wall and in the apex of the heart and of the participation of these regions in the formation of hemodynamic characteristics. Adrenaline caused similar effects whereas CaCl2 exerted different inotropic effects on the left ventricular wall and the apex of the heart. Changes in mechanical tension of the wall correlated with variations in the pressure inside the left ventricle. Tension in the apex of the heart produced alterations in the stroke volume.
