What is Bezold jerisch reflex????


Bezold Jarisch Reflex- sympathetic activity activates non-myelinated fibers at the base of left ventricle, these fibers mediate an efferent response that results in sympathetic withdrawal, hypotension & bradycardia.


Is this sympathatic or parasympahatic thru vagus nerve......????

Due to stimulation of stretch receptors in the left ventricle by distension of left ventricle....afferent thru Vagus N.
