To analyze the interaction of calcium ion concentration with hypertonic agents and with other inotropic interventions, isolated right ventricular cat papillary muscles were studied under isometric conditions in Krebs-Ringer bicarbonate solution. Extr

In cardiac muscle, moderate degrees of hyperosmolality of the type encountered physiologically or clinically (i.e., less than 200 mosM above control) characteristically exert a positive inotropic effect, which presumably is mediated by increased Ca2+

The direct inotropic effect of hypertonic mannitol was compared in isolated rat and cat papillary muscles. The inotropic effects of paired electrical stimulation and D600 were also evaluated in the same species. At extracellular calcium concentration

The influence on mechanical properties of changes in resting tension over a range from 0.5 to 4.5 g was investigated in 12 isolated cat papillary muscles. At each resting tension, the muscles contracted isometrically with the exception of an external

The data obtained from these studies demonstrate that the inotropic effect of hyperosmolar mannitol and sucrose and of paired electrical stimulation is critically influenced by extracellular calcium concentration. The inotropic effect of norepinephri
