Reflex Dannini

The Danini reflex is a cardiovascular reflex in which movement of the body or head causes changes in heart rate. This reflex was first described in 1873 by the French anatomist Henri-Emmanuel Dagnone. The reflex manifests itself in the form of increased heart rate and increased blood pressure when turning the head.

The essence of the Danya-Aschner reaction is a change in blood pressure and heart rate when the patient's head is tilted forward: in healthy people, heart rate slows down and blood pressure decreases, and in patients, characteristic manifestations of tachycardia and arterial hypertension appear.

The manifestation (reaction) of the reflex has diagnostic significance and allows one to distinguish CVS pathology from disorders of the nervous system, vestibular and auditory apparatus. The clinical significance of the Danyi-Aschner reflex lies in the fact that it can be used to diagnose diseases of the nervous and cardiovascular systems, as well as to monitor the patient’s condition during surgery.

The depressor reaction develops in connection with the mobilization of the sympathoadrenal system and its catecholamines; it also includes the Aschner-Dagnini and Tri reactions.
