摘要：

Studies were performed using the isolated supported heart to determine the myocardial effects of calcium chloride under relatively controlled hemodynamic conditions. The intracoronary infusion of calcium was associated with an increase in myocardial contractility and a net gain of potassium by the heart. These changes occurred in the presence of no consistent change in myocardial oxygen consumption. It is suggested that changes in myocardial potassium balance may reflect directional changes in myocardial calcium balance. © 1968.
