Orthostatic intolerance and chronic fatigue syndrome--possible related conditions.
The connection between orthostatic intolerance and chronic fatigue syndrome was first introduced in 1995. It was demonstrated that many patients with chronic fatigue syndrome also had some form of orthostatic intolerance. Some studies suggested that dysautonomia may be the common problem in patients with these syndromes. Although these conditions affect an important number of people, especially...
متن کاملHypocapnia is a biological marker for orthostatic intolerance in some patients with chronic fatigue syndrome
CONTEXT Patients with chronic fatigue syndrome and those with orthostatic intolerance share many symptoms, yet questions exist as to whether CFS patients have physiological evidence of orthostatic intolerance. OBJECTIVE To determine if some CFS patients have increased rates of orthostatic hypotension, hypertension, tachycardia, or hypocapnia relative to age-matched controls. DESIGN Assess b...
متن کاملVascular perturbations in the chronic orthostatic intolerance of the postural orthostatic tachycardia syndrome.
Chronic orthostatic intolerance is often related to the postural orthostatic tachycardia syndrome (POTS). POTS is characterized by upright tachycardia. Understanding of its pathophysiology remains incomplete, but edema and acrocyanosis of the lower extremities occur frequently. To determine how arterial and venous vascular properties account for these findings, we compared 13 patients aged 13-1...
متن کاملNeurocirculatory abnormalities in chronic orthostatic intolerance.
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 supine rest. METHODS AND RESULTS Adult patients referred for COI who had POTS (n=90, mean+/-SEM ag...
متن کاملOrthostatic intolerance: postural orthostatic tachycardia syndrome with overlapping vasovagal syncope.
A 28-year-old female with a history of situational syncope and a new-onset right sided hemiparesis is described. Tilt-up table test revealed the postural orthostatic tachycardia syndrome followed by vasovagal syncope. Neurological and internal medicine tests showed no particular disorders. The patient underwent autonomic physical training and the tilt-up test performed three months later showed...
