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.

A Scoping Review of Non‐Opioid Therapeutics for Opioid Withdrawal: Translational Relevance to Neonatal Opioid Withdrawal Syndrome (NOWS) Research

Clinical and Translational Science, Volume 19, Issue 5, May 2026.
ABSTRACT In the wake of the ongoing opioid epidemic, the incidence of neonatal opioid withdrawal syndrome (NOWS) has surged. While the short‐term effects of NOWS are well‐characterized, long‐term physiological and molecular consequences remain unclear.

From Postural Orthostatic Tachycardia Syndrome to Radiologically Isolated Syndrome [PDF]

, 2018
Background. Autonomic dysfunction is common in Multiple Sclerosis (MS) patients. Most spinal cord lesions entail some degree of autonomic nervous system dysfunction. MS patients may develop autonomic dysfunction later in their disease course. Methods. We

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,

Cardiac Origins of the Postural Orthostatic Tachycardia Syndrome

Journal of the American College of Cardiology, 2010
The purpose of this study was to test the hypothesis that a small heart coupled with reduced blood volume contributes to the postural orthostatic tachycardia syndrome (POTS) and that exercise training improves this syndrome.Patients with POTS have marked increases in heart rate during orthostasis.

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

Sympathetic dysfunction in vasovagal syncope and the postural orthostatic tachycardia syndrome

Frontiers in Physiology, 2014
Orthostatic intolerance is the inability to tolerate the upright posture and is relieved by recumbence. It most commonly affects young women and has a major impact on quality of life and psychosocial well being.

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.
