Abstract
Postural tachycardia syndrome is defined as the development of orthostatic symptoms without orthostatic hypotension. We report a 28-year-old female pa tient with postural tachycardia syndrome who exhibited palpitation, low-gra de fever and weight loss. Evaluation of autonomic nervous system functions showed that cardiovagal function was normal. Sweat response to acetylcholin e was decreased. Excessive blood pressure elevation was seen in phase IV of the Valsalva maneuver. Pathophysiologic factors in this case were consider ed to be alpha adrenergic denervation and beta adrenergic hyperresponsivene ss. It is important that this syndrome be widely recognized and properly di agnosed.
