Common syndromes of orthostatic intolerance.
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 effective upright activities. OH is one form of ...

متن کاملSyndromes of orthostatic intolerance and syncope in young adults
OBJECTIVE To explore the clinical and neuroendocrine characteristics of syndromes of orthostatic intolerance and syncope in young adults. METHODS Two hundred and thirty-six patients aged 18-40 years with orthostatic intolerance and/or syncope were examined by head-up tilt test (HUT). Plasma levels of epinephrine, norepinephrine, renin, C-terminal-pro-arginine-vasopressin (CT-proAVP), C-termin...
متن کاملCardiac sympathetic dysautonomia in chronic orthostatic intolerance syndromes.
BACKGROUND In postural tachycardia syndrome (POTS) and repeated neurocardiogenic presyncope (NCS), orthostatic intolerance occurs without persistent sympathetic neurocirculatory failure. Whether these conditions involve abnormal cardiac sympathetic innervation or function has been unclear. METHODS AND RESULTS Patients with POTS or NCS underwent measurements of neurochemical indices of cardiac...
متن کاملPediatric Disorders of Orthostatic Intolerance.
Orthostatic intolerance (OI), having difficulty tolerating an upright posture because of symptoms or signs that abate when returned to supine, is common in pediatrics. For example, ∼40% of people faint during their lives, half of whom faint during adolescence, and the peak age for first faint is 15 years. Because of this, we describe the most common forms of OI in pediatrics and distinguish bet...
