title: [Dysautonomic syncope. Diagnosis and treatment].
abstract: Inappropriate activation or disbalance of vasomotor reflexes may have a close relationship with the pathogenesis of disautonomic syndromes, a frequent underlying cause of recurrent syncope. A combined approach of meticulous historical data, physical examination and selected laboratory procedures may delineate the most common causes of recurrent syncope. Tests of autonomic function may be particularly helpful in the diagnosis of this entity. They include some non-invasive maneuvers such as stimulation of carotid sinus, Valsalva maneuver or tilt-table test. Therapy for this syndrome includes pharmacologic agents, surgical and radiotherapeutic maneuvers and atrioventricular sequential pacing. In this work we will present an overall formulation of the diagnostic evaluation and a therapy approach of the patient presenting with this complaint.
