Orthostasis

Under orthostasis ( ancient Greek ὀρθός orthos , German , upright ' and στάσις stasis , German , standing' , position ') is understood in the medicine the upright posture . It is also used as a short form for the orthostasis syndrome (also called orthostatic dysregulation ). Orthostatic hypotension is a disturbance in the regulation of blood pressure that occurs when changing to an upright position . This leads to dizziness , ringing in the ears , reduced physical and mental performance and, in the worst case, syncope .

The ability of the human body to adjust the blood pressure and thus the circulatory system in an upright position (sitting or standing) is called orthostatic adjustment or orthostasis reaction .

If the body is hung motionless for a long time in a safety harness , it can lead to a circulatory collapse or even to unconsciousness and death. This image is known as hanging trauma (orthostatic shock ).

One test of current fitness is the orthostatic heart rate test .
