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,

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.

Pyridostigmine in the treatment of postural orthostatic tachycardia syndrome

Turk Kardiyoloji Dernegi Arsivi-Archives of the Turkish Society of Cardiology, 2014
A 34-year-old female patient was admitted with the complaints of inability to stand upright, palpitations, dizziness, and fatigue in the upright posture for the last one year. She was found to stand upright for less than one minute without symptoms. Tilt table testing showed that, compared to baseline her heart rate increased 55 beats/min in the fifth ...

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 Clinical Practice Update for the Management of Patients With Disorders of Gut‐Brain Interaction and Altered Food Intake Behavior

Neurogastroenterology &Motility, Volume 38, Issue 5, May 2026.
ABSTRACT Background Disorders of Gut‐Brain Interaction (DGBI) impact as many as one in three individuals at some stage of their lives. Clinically, patients with DGBI may present with meal‐related symptoms that progressively lead to altered food intake behaviors, resulting in subsequent weight loss and nutritional deficiencies.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Exploring heart rate variability as a biomarker for frailty: A narrative review

European Journal of Clinical Investigation, Volume 56, Issue 4, April 2026.
Frailty arises from progressive multisystem dysregulation, prompting interest in biomarkers that capture declining physiological reserve. This review positions heart rate variability (HRV) within this evolving biomarker landscape, outlining its physiological basis, analytical domains and relevance to clinical research.

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.

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
