[Cardiovascular effects of histamine mediated by H1- and H2-receptors].
Histamine was found to suppress the myocardial contractile function, to decrease systemic arterial blood pressure and to exert a positive chronotropic effect in unanesthetized dogs. A preliminary blockade of H1-receptors prevented the hypotensive effect of histamine, blockade of H2-receptors prevented the development of the positive chronotropic effect.
