Bezold-Jarisch reflex

from Wikipedia, the free encyclopedia

The Bezold-Jarisch reflex is a reflex emanating from the heart muscle . The reflex was named after the German physiologist Albert von Bezold (1836–1868) and the Austrian pharmacologist Adolf Jarisch junior (1891–1965).

The Bezold-Jarisch reflex is regarded as a combination of a cardiocardial self-reflex ( bradycardia ) and a cardiovascular external reflex ( hypotension ). In addition to the irritation of stretch receptors, chemical irritation (e.g. in hypoxic conditions) in the left ventricle is suspected to be the cause.

Jarisch came across Albert von Bezold's investigations by chance because one of his employees regularly had sneezing attacks while pulverizing mistletoe leaves. This prompted Jarisch to read about the hellebore, where he found von Bezold's work on the effects of veratrin . Jarisch dealt intensively with this "Bezold effect", which he described, and published twelve further papers between 1939 and 1949 to elucidate the physiological and pharmacological mechanisms.

The term "Bezold-Jarisch-Reflex" is used for the first time in Schäfer. The exact reflex events have not yet been finally clarified.
