Overview
A cardiovascular depressor reflex involving a marked increase in vagal (parasympathetic) efferent discharge to the heart, elicited by stimulation of chemoreceptors, primarily in the left ventricle. This causes a slowing of the heart beat (bradycardia) and dilatation of the peripheral blood vessels with resulting lowering of the blood pressure. [1] [2] [3]
The concept was originated by Bezold in 1867, later revised by Jarisch in 1937.
