Effects of autonomic denervation on CAVB animals. One minute beating rate averages over time (n = 1), 10-minute mean heart rates before and after drug administration, and ∆ beating rates before and after administration of (A) 3 mg/kg atropine, (B) 3 mg/kg propranolol, or (C) 3 mg/kg atropine and 3 mg/kg propranolol in sinus rhythm (SR) (n = 5) and CAVB (n = 4) models. Bar graphs include standard error bars.
