title: [An experimental study of the pharmacological activity of opiate receptor ligands on models of adrenaline-induced arrhythmias].
abstract: The influence of intracerebroventricular injection of opioid peptides on the incidence and severity of ventricular arrhythmia induced by intravenous administration of epinephrine was studied. It was found that DAGO, a selective mu-agonist, and DADLE, a nonselective delta-agonist, reduce the incidence and severity of cardiac arrhythmia in rats. On the contrary, DSLET, a selective delta-agonist, and Dynorphin A 1-13 (kappa-agonist), potentiates epinephrine-induced arrhythmias. beta-Endorphin do not affect the arrhythmia. The activation of cerebral mu-opioid receptors is shown to prevent the appearance of arrhythmia. On the contrary, the activation of delta- and kappa-receptors induces the appearance of arrhythmia.
