Postural Orthostatic Tachycardia Syndrome (POTS)--A novel member of the autoimmune family.
Postural orthostatic tachycardia syndrome (POTS) is a heterogeneous disorder of the autonomic nervous system in which a change from the supine position to an upright position causes an abnormally large increase in heart rate or tachycardia (30 bpm within 10 min of standing or head-up tilt). This response is accompanied by a decrease in blood flow to the brain and hence a spectrum of symptoms as...
متن کاملNeuronal and hormonal perturbations in postural tachycardia syndrome
The Postural Tachycardia Syndrome (POTS) is the most common disorder seen in autonomic clinics. Cardinal hemodynamic feature of this chronic and debilitating disorder of orthostatic tolerance is an exaggerated orthostatic tachycardia (≥30 bpm increase in HR with standing) in the absence of orthostatic hypotension. There are multiple pathophysiological mechanisms that underlie POTS. Some patient...
متن کاملPostural Tachycardia Syndrome and Inappropriate Sinus Tachycardia: Role of Autonomic Modulation and Sinus Node Automaticity
BACKGROUND Inappropriate sinus tachycardia (IST) and postural tachycardia syndrome (POTS) are 2 disorders characterized by sinus tachycardia. It is debated whether the pathophysiology of IST and POTS results from abnormal autonomic regulation or abnormal sinus node function. We hypothesized that intrinsic heart rate (IHR) after autonomic blockade would be increased in patients with IST but not ...
متن کاملThe Postural Tachycardia Syndrome (POTS): Pathophysiology, Diagnosis & Management
Postural tachycardia syndrome (POTS), characterized by orthostatic tachycardia in the absence of orthostatic hypotension, has been the focus of increasing clinical interest over the last 15 years 1. Patients with POTS complain of symptoms of tachycardia, exercise intolerance, lightheadedness, extreme fatigue, headache and mental clouding. Patients with POTS demonstrate a heart rate increase of ...
متن کاملPostural orthostatic tachycardia syndrome in a patient with relapsing-remitting optic-spinal multiple sclerosis: A case report and discussion of possible mechanism
Postural orthostatic tachycardia syndrome (POTS) is characterized by orthostatic intolerance, a presentation of autonomic dysfunction which is frequently observed in the patients with multiple sclerosis (MS). Nevertheless, to date, there have been a few studies focusing on POTS in MS patients and the underlying pathomechanism. We present a 28-year-old woman with relapsing-remitting opticspinal ...
