Orthostatic hypotension, also known as postural hypotension, [2] is a medical condition wherein a person's blood pressure drops when they are standing up (orthostasis) or sitting down. Primary orthostatic hypotension is also often referred to as neurogenic orthostatic hypotension. [ 3 ]
Orthostatic vital signs are also taken after surgery. [7] A patient is considered to have orthostatic hypotension when the systolic blood pressure falls by more than 20 mm Hg, the diastolic blood pressure falls by more than 10 mm Hg, or the pulse rises by more than 20 beats per minute within 3 minutes of standing [5] [7]
In reality, orthostatic hypotension can cause vague symptoms (e.g. dizziness) which are similar to those caused by VBI; VBI should only be considered where the stenosis is severe and/or there are focal neurological symptoms specific to the posterior circulation. [6] VBI may also result from altered blood flow as seen in subclavian steal syndrome.

The majority of symptoms that patients with PAF exhibit are associated with neurogenic orthostatic hypotension, or orthostatic hypotension brought on by severe sympathetic failure. Within three minutes of standing up straight, orthostatic hypotension is defined as a drop in systolic blood pressure of at least 20 mm Hg or a drop in diastolic ...
Orthostatic syncope refers to syncope resulting from a postural decrease in blood pressure, termed orthostatic hypotension. [1]Orthostatic hypotension occurs when there is a persistent reduction in blood pressure of at least 20mmHg systolic or 10mmHg diastolic within three minutes of standing or being upright to 60 degrees on the head-up tilt table.
Patients with NOH have depleted levels of norepinephrine which leads to decreased blood pressure or hypotension upon orthostatic challenge. [14] Droxidopa works by increasing the levels of norepinephrine in the peripheral nervous system (PNS), thus enabling the body to maintain blood flow upon and while standing. [14]
