http://peripheral-nerve-block.com/category5/entry50.html WebThe concept of depressor reflexes originating in the heart was introduced by von Bezold in 1867 and was later revived by Jarisch. The Bezold-Jarisch reflex originates in cardiac sensory receptors with nonmyelinated vagal afferent pathways. The left ventricle, particularly the inferoposterior wall, is a principal location for these sensory ...

This observation was comparatively neglected until Jarisch and Henze re-examined it in 1937; they identified the reaction as a chemoreflex acting via the vagus ne… http://www.peripheral-nerve-block.com/category3/entry35.html h1t-box
