Abstract

Intravenous injection of 10 mg/kg anandamide reduces the incidence and duration of epinephrine-induced arrhythmias in rats. SR141716A and SR144528, antagonists of cannabinoid receptor I and II did not abolish the antiarrhythmic effect of anandamide. These data suggest that the antiarrhythmic effect of anandamide is nonspecific or mediated via unknown cannabinoid receptors, but not associated with activation of cannabinoid receptors I and II.
