Orthostatic hypertension is a medical condition consisting of a sudden and abrupt increase in blood pressure (BP) when a person stands up. [1] Orthostatic hypertension is diagnosed by a rise in systolic BP of 20 mmHg or more when standing.
The basic physiological change that occurs in the body during prolonged standing or sudden stand from supine position is that there will be increased pooling of blood in the legs. This decreases the venous return, and so there will be decreased cardiac output, which ultimately causes systolic blood pressure to fall (hypotension).
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]
