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

Children and adolescents with disorders of gut–brain interaction with comorbid hypermobility and orthostatic intolerance have worse outcomes

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 6, Page 1394-1399, June 2026.
Abstract Objectives Disorders of gut–brain interaction (DGBI) affect about 40% of children and are often comorbid with hypermobility spectrum disorders (HSDs) and orthostatic intolerance (OI). However, how these comorbidities impact outcomes in pediatric DGBI is not well understood.

Other Syndromes of Orthostatic Intolerance: Delayed Orthostatic Hypotension, Postprandial Hypotension, Postural Orthostatic Tachycardia Syndrome, and Reflex Syncope

, 2020
Apart from classical orthostatic hypotension, the gravitational force may strongly contribute to other forms of orthostatic intolerance, delayed and postprandial OH, postural orthostatic tachycardia syndrome (POTS), and reflex syncope. In delayed OH, the

Postural Tachycardia Syndrome: Beyond Orthostatic Intolerance [PDF]

Current Neurology and Neuroscience Reports, 2015
Postural tachycardia syndrome (POTS) is a form of chronic orthostatic intolerance for which the hallmark physiological trait is an excessive increase in heart rate with assumption of upright posture. The orthostatic tachycardia occurs in the absence of orthostatic hypotension and is associated with a >6-month history of symptoms that are relieved by ...

Cardiovascular Health in Women—Across the Lifespan

Clinical Endocrinology, Volume 104, Issue 6, Page 539-555, June 2026.
ABSTRACT Cardiovascular disease (CVD) remains the leading cause of mortality and morbidity among women worldwide. However, CVD continues to be perceived as a predominantly male issue. CVD in women therefore remains understudied, underrecognized and undertreated.
