Autonomic control of resting heart rate was assessed using atropine and propranolol in 20 neonatal (2 to 3 weeks old) male Rhesus monkeys. After release from restraint for placement of a venous catheter, the average heart rate significantly decreased from 220 ± 7 beats/min to 181 ± 6 beats/min within 15 minutes and remained stable for the 2 hours. Autonomic control of resting heart rate is mediated through both divisions of the autonomic nervous system with the sympathetic system having a dominant influence. This is in contrast to the adult Rhesus, where the parasympathetic nervous system controls resting heart rate.
