Introduction
Introduction This condition is common in orthostatic hypotension: orthostatic hypotension is due to changes in body position, such as a sudden change from supine position to erect or low blood pressure that occurs over a long period of time. It is generally believed that post-stiction systolic blood pressure drops 20 mm Hg or a diastolic blood pressure drops 10 mm Hg, which is orthostatic hypotension. Orthostatic hypotension is divided into two types: sudden and secondary.
