Abstract

The experiments done on the isolated right ventricle of rat heart suspended in the bath for isolated organs with oxygenated Tyrode's solution showed the PgI2 (2.3 x 10-6 mmol) produced its positive inotropic effect indirectly by promoting both beta-adrenoreceptors and calcium entry through slow calcium channels because this effect could be blocked by propranolol (2.3 x 10-2 mmol - beta-adrenoreceptor blocker) or verapamil (4.3 x 10-3 mmol - slow calcium channel blocker).
