ORTHOSTATIC HYPOTENSION AND ORTHOSTATIC TACHYCARDIA
Journal of the American Medical Association, 1940Orthostatic hypotension is characterized chiefly by a sharp decrease in blood pressure when a patient afflicted with it stands. The blood pressure is ordinarily normal when the patient lies. If the blood pressure decreases to a low level, weakness and syncope result.

The commonest form is vasodepressor syncope, with an active dilatation of resistance vessels, indicative of a crescendo, autonomic discharge in which cholinergic features predominate (perspiration, increased ...

Prevalence of orthostatic hypotension
Clinical Autonomic Research, 2008Orthostatic hypotension (OH) is defined as a fall in blood pressure of at least 20 mmHg systolic or 10 mmHg diastolic when standing or during head-up tilt testing. The prevalence of OH increases with age, with disorders that affect autonomic nerve transmission, and with increasingly severe orthostatic stress.
