Carotid sinus nerve stimulation effects on coronary resistance in dogs remain hypothesis-generating; human studies needed before clinical relevance.
Does carotid sinus nerve stimulation alter coronary circulation and resistance in conscious dogs?
Carotid sinus nerve stimulation causes coronary dilatation in conscious dogs by reducing resting sympathetic constrictor tone.
Vatner et al. (1970) studied this question.
