The autonomic nervous system (ANS) controls all body functions. Dysregulation of this system may be responsible of Orthostatic intolerance (OI). OI forms may coexist in the same patients. So we report a 24-year-old female case who suffers from coexisting features of postural tachycardia syndrome (POTS) and neurocardiogenic syncope (NCS). Through this case we describe the clinical features and management of this autonomic disorder. The patient reported clinical symptoms consistent with both POTS and NCS and then demonstrated typical POTS (a rise in heart rate (HR) without change in blood pressure [BP]) within the first 10 minutes of upright posture followed by neurocardiogenic syncope (a sudden fall in HR and BP). The treatment (hygienodietetic measures, fludrocortisone) showed an improvement in the functional state of the patient. NCS may coexist with POTS in a subgroup of patients suffering from OI. Autonomic profile study helps to explain the causes of symptoms described by this patient with whose clinical and conventional paraclinical examinations are normal.
