[Orthostatic hypotension. Case report of the Bradbury-Eggleston syndrome].

: A case of a 71-year-old woman with idiopathic orthostatic hypotension is presented. Several diagnostic procedures which can detect sympathetic pathway lesion are reported. The value of blood pressure measurement and heart rate response to the supine and standing position deep breath, Valsalva maneuver and cold pressor test in differential diagnosis are emphasized. The venoconstriction, venous reflexes and tyramine tests are described, as well. The authors favour an individual therapeutic approach with no limitation of mineralocorticoid dosage. Nonpharmacological measures, such as an increased salt intake, elastic support stockings and swimming are highly recommended.
