ABSTRACT
There is no doubt that the effects of the catecholamines of the heart are mainly due to the stimulation of beta-adrenoceptors but in the mid 1960' s the first evidence was presented that a-adrenoceptors mediating positive inotrpoism exists also in the myocardium beside well established beta -adrenoceptors. In our observation adrenaline shows a positive inotropic response. The response of adrenaline in presence of metoprolol [beta1blocker] showed negative inotropic effect
