Effects of isoprenaline and aminophylline on the chronotropic responses of the isolated guinea-pig heart to vagal stimulation and acetylcholine
1. In isolated perfused guinea-pig hearts, isoprenaline (2 × 10(-8) g/ml) reduced the negative chronotropic responses to vagal stimulation and to exogenous acetylcholine. 2. The β-adrenoceptor antagonist LB46 (2 × 10(-8) g/ml) abolished the effect of isoprenaline in reducing vagal bradycardia. LB46...
