Résumé
The participation of ß2-adrenoceptors in the chronotropic response was evaluated in righ atria isolated from rats submitted to daily footshock stress for three days. Footshock increased both the sensitivity to salbutamol and the pA2 of butoxamine. These results provide additional support for the proposal that repeated footshock stress increases the functional of rat atrial postjunctional ß2-adrenoceptors
