ABSTRACT
We studied the effects of selective blockade of various subtypes of α2-adrenoceptors on cardiac chronotropy in newborn rats. This period in rats is characterized by the absence of adrenergic regulation of heart function. Blockade of α2A/D- and α2B-adrenoceptors in 1-weekold rats provoked tachycardia. In contrast, blockade of α2C-adrenoceptors in newborn rats had no effect on heart rate.
