Orthostatic hypotension and birthweight
Archives of Gynecology and Obstetrics, 1991This study was designed to test two hypotheses. First, that the changes in arterial blood pressure, induced by a transition from a lying to a standing position, are different in early and late pregnancy. Second, that birthweight is related to the change in mean arterial blood pressure in late pregnancy such that those patients whose pressure fell on ...

Orthostatic Hypotension and Syncope
New England Journal of Medicine, 1977A failure of peripheral vascular tone in the upright position is a common cause of arterial hypotension, cerebral ischemia and syncope. 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 ...

Idiopathic Orthostatic Hypotension
JAMA: The Journal of the American Medical Association, 1962Six patients with idiopathic orthostatic hypotension were studied for the effect and mode of action of 9-alpha-fluorohydrocortisone. In 5 patients satisfactory symptomatic control of the hypotension was achieved. In 1 patient it was twice demonstrated that the rise of blood pressure obtained within 48 hours after starting treatment with 9-alpha ...

Hypotension Unawareness in Profound Orthostatic Hypotension
The American Journal of Medicine, 2009Clinicians depend on history given by the patients when considering the diagnosis of orthostatic hypotension.Patients with a decrease in systolic blood pressure more than 60 mm Hg from baseline during a head-up tilt table test were included. They were classified according to their symptoms during the head-up tilt table test.

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.

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.
