Orthostatic hypertension.
A 40 year old man was found to have marked hypertension when he was in the upright position with normal pressures when he was supine. Investigations disclosed normal catecholamine and renin levels. The baroreceptor reflex was somewhat depressed. The mechanism of this orthostatic hypertension is not known. The condition has not been reported previously.
