Abstract Background: Postural tachycardia syndrome (POTS) is characterized by excessive upright tachycardia and disabling presyncopal symptoms, which are exacerbated after consuming a high-carbohydrate meal; it is unknown, however, what is the precise underlying mechanism. We seek to...

Abstract Purpose Previous studies demonstrated M2 muscarinic acetylcholine receptor-activating autoantibodies (M2R-AAb) were present in some patients with postural tachycardia syndrome (POTS). This study examines how these autoantibodies might contribute to the pathophysiology of POTS, and...

Abstract In normal subjects natriuresis is tightly coupled to dietary salt ingestion to maintain sodium balance. Likewise, blood pressure remains unchanged over a wide range of salt intake because of pressure natriuresis, whereby an increase in blood pressure stimulates renal sodium excretion...

Gluten-free diet in postural orthostatic tachycardia syndrome (POTS), 2022, Zha et al Abstract Objectives Postural orthostatic tachycardia syndrome (POTS) is a chronic disorder of the autonomic nervous system that is associated with orthostatic intolerance (OI) and gastrointestinal (GI)...

This came into my mailbox. i thought i’d share. Full text here . Interestingly the authors are affiliated to King’s College in London. Abstract Background: There have been previous reports of enhanced sympathoexcitation in autism spectrum disorder (ASD). However, there has been no formal...

The postural tachycardia syndrome, or PoTS, was named and defined in 1993,1 but is likely synonymous with earlier conditions such as ‘The Soldier’s Heart’, a term coined by Sir James Mackenzie in 1916.2 Affected patients experience an abnormal response to upright posture resulting in multiple...

Orthostatic Symptoms and Reductions in Cerebral Blood Flow in Long-Haul COVID-19 Patients: Similarities with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Abstract Background and Objectives: Symptoms and hemodynamic findings during orthostatic stress have been reported in both long-haul...

Highlights Long COVID symptoms include fatigue, brain fog, anosmia, dysgeusia, orthostatic intolerance Long COVId symptoms overlap with those of chronic fatigue syndrome (ME/CFS) and POTS. Reduced cerebral blood flow is a feature of dysautonomia in ME/CFS and POTS. Stellate ganglion block...

Abstract As part of the non-criteria clinical manifestations, postural orthostatic tachycardia syndrome (POTS), a multisystem autonomic dysfunction, can co-exist with antiphospholipid syndrome (APS). Several pieces of evidence hint on the autoimmune basis of POTS, and its possible association...

ABSTRACT There is limited literature on the cardiovascular manifestations of post-acute sequelae of SARS-CoV-2 infection (PASC). We aimed to describe the characteristics, diagnostic evaluations, and cardiac diagnoses in patients referred to a cardiovascular disease clinic designed for patients...

Objective: To investigate the influence of comorbidities on the prognosis of pediatric postural tachycardia syndrome (POTS). Methods: In this retrospective cohort study, 275 children with POTS admitted to the Department of Pediatrics at Peking University First Hospital were recruited from 2016...

Introduction SARS-CoV-2 infection which causes the disease COVID-19 is most known for its severe respiratory complications. However, a variety of extrapulmonary effects have since been described, with cardiovascular complications being amongst the most common[1]. Those who recover from the acute...

Orthostatic intolerance syndromes after hematopoietic cell transplantation: clinical characteristics and therapeutic interventions in a single-center experience Abstract Background Hematopoietic cell transplantation (HCT) is an established and potentially curative therapeutic option for...

Abstract There is a small yet robust body of literature regarding autonomic dysfunction in Idiopathic hypersomnia (IH) as well as sleep disturbances in Postural Orthostatic Tachycardia Syndrome (POTS). This review aims at summarizing the current literature and highlighting gaps in the current...

Hi all, I can see that this is not the most active part of the forum, but thought I'd ask anyhow.. So, I've been seen by a well renowned cardiologist in London, who, has done oodles of tests to rule in/out POTS/IST etc. and, having done a TTT and CPET (only a single day sadly, but, which I did...

Abstract Background Postural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance that primarily impacts female patients of childbearing age. The role of sex differences in POTS is not well understood. We sought to identify sex differences in diagnosis, symptoms...

Abstract Postural orthostatic tachycardia syndrome (POTS) is a disorder epitomized by the story of the blind men and the elephant. Patients may see primary care internists or pediatricians due to fatigue, be referred to neurologists for “spells”, to cardiologists for evaluation of pre-syncope...
