Why the study?
Do high plasma catecholamines interfere with the sympathetic neural regulation of heart rate in anesthetized rabbits?
Do high plasma catecholamines interfere with the sympathetic neural regulation of heart rate in anesthetized rabbits?
High plasma concentrations of noradrenaline and adrenaline do not interfere with the dynamic sympathetic neural regulation of heart rate, demonstrating robustness of the neural control system.

Preserved sympathetic HR control despite high catecholamines in rabbits; leaves open translation to conscious or human physiology.
Kawada et al. (2006) studied this question.
