Abstract
In order to study cardiac function many investigators use isolated heart preparations perfused with saline solutions. In isolated rabbit heart perfused with a Tyrode solution at 37 °C it has been shown that oxygen supply is partially limiting oxygen consumption1. Experiments with isolated Tyrode perfused rabbit hearts at 28 °C proved that oxygen supply was not limiting. This finding has been explained by increased oxygen solubility and decreased metabolic demand at the lower temperature2.
