Orthostatic hypertension: An underestimated cause of orthostatic intolerance

Clinical Neurophysiology, 2016
To investigate the frequency and mechanism of orthostatic hypertension (OHT) in patients with orthostatic intolerance.We retrospectively reviewed 1033 consecutive case series of orthostatic intolerance that underwent autonomic function tests including a head-up tilt test. OHT was defined as a paradoxical orthostatic increase in systolic blood pressure (

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.

The Application of Head-Up Tilt Test to Diagnose Hemodynamic Type of Orthostatic Intolerance in Children Aged Between 3 and 5 Years

Frontiers in Pediatrics, 2021
Objectives: The head-up tilt test (HUTT) is a useful tool to assess autonomic function and to reproduce neurally mediated reflex. In this study, we evaluated the use of HUTT in pediatric patients aged 3–5 years with orthostatic intolerance. Materials and

Cardiovascular Autonomic Dysfunction Is the Most Common Cause of Syncope in Paced Patients

Frontiers in Cardiovascular Medicine, 2019
Introduction: Syncope and orthostatic intolerance in paced patients constitute a common clinical dilemma. We, thus, aimed to determine the etiology of syncope and/or symptoms of orthostatic intolerance in paced patients.Methods: Among 1,705 patients with

Severe orthostatic hypotension in otherwise uncomplicated Plasmodium vivax infection

Malaria Journal, 2021
Impaired autonomic control of postural homeostasis resulting in orthostatic hypotension has been described in falciparum malaria. However, severe orthostatic intolerance in Plasmodium vivax has been rarely reported.

An Unusual Case of Polyautoimmunity with Concomitant Presentation of Postural Tachycardia Syndrome, Antiphospholipid Syndrome and Hashimoto’s Thyroiditis

Clinical and Translational Neuroscience, 2021
Introduction: Postural tachycardia syndrome (POTS) is a chronic form of autonomic dysfunction characterized by symptoms of orthostatic intolerance, often accompanied by sudomotor dysfunction and gastrointestinal dysmotility.

Syndromes of orthostatic intolerance: a hidden danger [PDF]

Journal of Internal Medicine, 2013
AbstractOrthostatic hypotension (OH) is a relatively common heterogenous and multifactorial disorder, traditionally classified as neurogenic (less common but often more severe) or nonneurogenic (more common, with no direct signs of autonomic nervous system disease).

Prevalence of orthostatic intolerance in long covid clinic patients and healthy volunteers: A multicenter study

Journal of Medical Virology
Orthostatic intolerance (OI), including postural orthostatic tachycardia syndrome (PoTS) and orthostatic hypotension (OH), are often reported in long covid, but published studies are small with inconsistent results.
