The Postural Tachycardia Syndrome (POTS): Pathophysiology, Diagnosis & Management [PDF]

, 2006
Postural tachycardia syndrome (POTS), characterized by orthostatic tachycardia in the absence of orthostatic hypotension, has been the focus of increasing clinical interest over the last 15 years 1. Patients with POTS complain of symptoms of tachycardia,

Patients with Orthostatic Intolerance: Relationship to Autonomic Function Tests results and Reproducibility of Symptoms on Tilt

Scientific Reports, 2017
This study was designed to investigate the frequency and pattern of orthostatic symptoms during head-up tilt (HUT) in patients with orthostatic intolerance during daily life, and to identify the relationship between the orthostatic symptoms during HUT ...

Cerebral Oximetry in Syncope and Syndromes of Orthostatic Intolerance

Frontiers in Cardiovascular Medicine, 2019
Cerebral autoregulation is crucial for maintaining cerebral blood flow and perfusion. In recent years, the importance of cerebral oxygenation in syncope and orthostatic intolerance (OI) has received increased attention. Cerebral tissue oxygenation can be

Neurocirculatory Abnormalities in Chronic Orthostatic Intolerance [PDF]

Circulation, 2005
Background— Chronic orthostatic intolerance (COI) occurs in postural tachycardia syndrome (POTS) and in some individuals with repeated neurocardiogenic syncope/presyncope (NCS), without POTS. This study addressed whether patients with COI and POTS or NCS have neurocirculatory abnormalities during ...

A phenomap of TTR amyloidosis to aid diagnostic screening

ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

The Management of Parkinson's Disease Before, during and after Pregnancy—an MDS Scientific Issues Committee Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Pregnancy after a Parkinson's diagnosis presents complex challenges. Due to the paucity of literature, there is no evidence‐based guidelines and protocols for preconception care, management of pregnancy, childbirth and the postpartum period in women with early‐onset Parkinson's disease (PD).

Sympathetic Shift and Insular Alteration: Unravelling the Link Between Anxiety and Heart Rate Variability in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Anxiety and autonomic dysfunction are frequent non‐motor symptoms of Parkinson's disease (PD). Their relationship, as well as the neural mechanisms underlying this relationship, remain unexplored. Objectives We aimed to investigate the relationship between cardiovascular functions and anxiety in PD and the structural neural changes ...

Common Syndromes of Orthostatic Intolerance [PDF]

Pediatrics, 2013
The autonomic nervous system, adequate blood volume, and intact skeletal and respiratory muscle pumps are essential components for rapid cardiovascular adjustments to upright posture (orthostasis). Patients lacking sufficient blood volume or having defective sympathetic adrenergic vasoconstriction develop orthostatic hypotension (OH), prohibiting ...

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 ...
