Orthostatic Intolerance: Orthostatic Hypotension and Postural Orthostatic Tachycardia Syndrome



In health, movement from lying or sitting to standing is largely unassociated with evident change in well-being. However, in some individuals, especially those who are physically deconditioned, there may be a transient sense of increased heart rate. In others, a brief “grey-out” of vision may occur from time to time, but this sensation usually disappears quickly (perhaps <10 s) and does not occur consistently. On the other hand, if symptoms of near-syncope or syncope develop repetitively, or if patients begin to complain of symptoms suggestive of sympathetic autonomic hyperactivity (e.g., palpitations, heart racing, and anxiety) with movement to the upright posture, then they may be considered to be exhibiting orthostatic intolerance.
