Abstract Objective Orthostatic intolerance is typically thought to be sporadic and attributed to cerebral autonomic dysfunction; we sought to identify families with inherited autonomic dysfunction manifest as symptomatic orthostatic intolerance to characterize mode of inheritance and clinical...

Looking forward The opportunities for further clinical research into autonomic medicine are too numerous to list. However, by pointing to a number of strategic areas, I hope to stimulate thought and catalyze ideas for potential research projects: • Well-designed epidemiologic studies are needed...

Abstract Background: As complaints of long-haul COVID patients are similar to those of ME/CFS patients and as orthostatic intolerance (OI) plays an important role in the COVID infection symptomatology, we compared 14 long-haul COVID patients with 14 ME/CFS patients with a post-viral Ebstein-Barr...

Objectives The Institute of Medicine (IOM 2015. Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness. Washington: The National Academies Press) suggested new criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), which requires an endorsement of...

(An old study, but one that deserves to be remembered as it addresses the question of whether the increased heart rate of POTS could be caused by a fear of standing. Yes, that idea sounds ridiculous but a recent paper proposed it. Thanks to Sid for bringing this 2007 paper to our attention.)...

Summary Orthostatic hypotension is an unusually large decrease in blood pressure on standing that increases the risk of adverse outcomes even when asymptomatic. Improvements in haemodynamic profiling with continuous blood pressure measurements have uncovered four major subtypes: initial...

Abstract Postural Orthostatic Tachycardia Syndrome (POTS) is a complex, multisystem disorder characterized by orthostatic intolerance and tachycardia and may be triggered by viral infection. Recent reports indicate 2-14% of COVID-19 survivors develop POTS and 9-61% experience POTS-like...

Background: Orthostatic intolerance (OI) is a core finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Deconditioning is often proposed as an important determinant for OI. Deconditioning can be objectively classified using the predicted peak oxygen...

Background: Some patients with acute COVID-19 are left with persistent, debilitating fatigue, cognitive impairment (“brain fog”), orthostatic intolerance (OI) and other symptoms (“Long COVID”). Many of the symptoms are like those of other post-infectious fatigue syndromes and may meet criteria...

The YouTube link below relates to the April 8 online talk and Q&A with Professor Frans Visser and Dr Linda van Campen who are both Dutch experts/cardiologists/clinicians/researchers. This talk and Q&A session was arranged by the Irish ME Trust and the Irish ME/CFS Association. Q&A was edited...

Abstract Purpose Bolus water drinking, at room temperature, has been shown to improve orthostatic tolerance (OT), probably via sympathetic activation; however, it is not clear whether the temperature of the water bolus modifies the effect on OT or the cardiovascular responses to orthostatic...

Abstract Background: Patients with PASC often report symptoms of orthostatic intolerance and autonomic dysfunction. Numerous case reports link Postural Orthostatic Tachycardia Syndrome (POTS) to PASC. No prospective analysis has been performed. Objective: We performed head-up tilt table (HUTT)...

Women are more prone to orthostatic intolerance compared to men and have a greater vasodilatory capacity. We investigated the hypothesis that women would have greater peripheral flow-mediated dilation (FMD) while in the upright posture compared to men, which could contribute to this phenomenon...
