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

Long‐term outcomes in patients with postural orthostatic tachycardia syndrome with an average follow‐up of over 20 years

Journal of Internal Medicine, EarlyView.
Abstract Background Postural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance that primarily affects female patients. There are scarce data evaluating the long‐term outcomes in POTS. Objectives This study sought to evaluate the long‐term impacts of POTS over multiple decades in adult patients.

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 ...
