description

Experiments in isolated cat hearts showed, that with increased Ca++-concentration of the perfusion-medium (0,56 g CaCl2/1000 ml) the onset of mechanical systole of left ventricle occurred earlier (21,9±3,3 msec after the onset ofQRS-complex in the ECG) than in experiments with a normal Ca++-concentration (0,28 g CaCl2/1000 ml). The onset of mechanical systole of the right ventricle was not effected.
