Cardiac norepinephrine output during carotid body stimulation.
In a series of 7 dogs, selective stimulation of the carotid body receptors by hypoxic blood produces an increase of coronary flow and greater release of norepinephrine from the heart; the increase of coronary flow is less marked and the release of norepinephrine is increased after vagotomy. Myocardial norepinephrine content is decreased by carotid body stimulation.
