Perioperative care of an adolescent with postural orthostatic tachycardia syndrome

Saudi Journal of Anaesthesia, 2010
Postural orthostatic tachycardia syndrome (POTS) is a disorder characterized by postural tachycardia in combination with orthostatic symptoms without associated hypotension. Symptoms include light-headedness, palpitations, fatigue, confusion, and anxiety,

Cooccurrence of Postural Orthostatic Tachycardia Syndrome with Two Different Clinical Entities

Case Reports in Pediatrics, 2016
Postural orthostatic tachycardia syndrome (POTS) is an abnormal heart rate response to a positional change. Several potential mechanisms for pathophysiology of POTS are defined. This syndrome can coexist with different clinical situations. In our report,

Reduced Stroke Volume and Brain Perfusion Drive Postural Hyperventilation in Postural Orthostatic Tachycardia Syndrome

JACC: Basic to Translational Science
Summary: Postural hyperventilation has been implicated as a cause of postural orthostatic tachycardia syndrome (POTS), yet the precise mechanisms underlying the heightened breathing response remain unclear.

Total blood volume and red blood cell volume are not associated with orthostatic intolerance in adults with myalgic encephalomyelitis/chronic fatigue syndrome

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Orthostatic intolerance is common in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and may worsen daily functioning. Although hypovolemia has been proposed as a contributor, its relationship to objective orthostatic abnormalities remains uncertain.

Postural orthostatic tachycardia syndrome in children and adolescents [PDF]

Autonomic Neuroscience, 2018
Postural orthostatic tachycardia syndrome (POTS) affects up to 3,000,000 people in the United States, with at least one-third of them developing POTS before the age of 18. POTS as a disorder is similar in adult and pediatric populations, but there are factors specific to pediatric patients that affect how it presents and how it is experienced that make

Neuronal and hormonal perturbations in postural tachycardia syndrome

Frontiers in Physiology, 2014
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

Orthostatic intolerance with tachycardia (postural tachycardia syndrome) and without (hypocapnic cerebral hypoperfusion) represent a spectrum of the same disorder

Frontiers in Neurology
BackgroundSpectrum of chronic orthostatic intolerance without orthostatic hypotension includes postural tachycardia syndrome (POTS), with orthostatic tachycardia and hypocapnic cerebral hypoperfusion (HYCH), without orthostatic tachycardia.

Postural tachycardia syndrome and other forms of orthostatic intolerance in Ehlers-Danlos syndrome

, 2018
Objective: To review the association between orthostatic intolerance syndromes and both joint hypermobility and Ehlers-Danlos syndrome, and to propose reasons for identifying hereditary connective tissue disorders in those with orthostatic intolerance in
