Postural (Orthostatic) Hypotension
Postural hypotension (Table 2) is defined as a decline of ≥20 mm Hg in the systolic BP, and/or a decline of ≥10 mm Hg in the diastolic BP, or an increase of ≥20 beats/minute in pulse rate, and abrupt symptoms of cerebral ischemia (syncope) following postural change from a supine to an upright position. It may be secondary to impaired homeostatic mechanisms of blood pressure regulation; age and/or cardiovascular-disease-related physiological changes; anti-hypertensive medications; and/or recent intake of food.
