Postural Orthostatic Tachycardia Syndrome: Mechanisms and New Therapies.

08:00 EDT 14th August 2019 | BioPortfolio

Summary of "Postural Orthostatic Tachycardia Syndrome: Mechanisms and New Therapies."

Postural orthostatic tachycardia syndrome (POTS) is a clinically heterogeneous disorder with multiple contributing pathophysiologic mechanisms manifesting as symptoms of orthostatic intolerance in the setting of orthostatic tachycardia (increase in heart rate by at least 30 beats per minute upon assuming an upright position) without orthostatic hypotension. The three major pathophysiologic mechanisms include partial autonomic neuropathy, hypovolemia, and hyperadrenergic state. Patients often will exhibit overlapping characteristics from more than one of these mechanisms. The approach to the treatment of POTS centers on treating the underlying pathophysiologic mechanism. Stockings, abdominal binders, and vasoconstrictors are used to enhance venous return in partial neuropathic POTS. Exercise and volume expansion are the main treatment strategies for hypovolemic POTS. For hyperadrenergic POTS, beta-blockers and avoidance of norepinephrine-reuptake inhibitors is important. Attempts should be made to discern which pathophysiologic mechanism(s) may be afflicting patients so that treatment regimens can be individualized. Expected final online publication date for the , Volume 71 is January 27, 2020. Please see for revised estimates.

Medical and Biotech [MESH] Definitions

A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright.

Symptoms of cerebral hypoperfusion or autonomic overaction which develop while the subject is standing, but are relieved on recumbency. Types of this include NEUROCARDIOGENIC SYNCOPE; POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME; and neurogenic ORTHOSTATIC HYPOTENSION. (From Noseworthy, JH., Neurological Therapeutics Principles and Practice, 2007, p2575-2576)

A partial adrenergic agonist with functional beta 1-receptor specificity and inotropic effect. It is effective in the treatment of acute cardiac failure, postmyocardial infarction low-output syndrome, shock, and reducing orthostatic hypotension in the Shy-Drager syndrome.

Therapies using arts or directed at the senses.

Adverse drug effects associated with CHOLINERGIC ANTAGONISTS. Clinical features include TACHYCARDIA; HYPERTHERMIA; MYDRIASIS, dry skin and dry mucous membranes, decreased bowel sounds and urinary retention in peripheral anticholinergic syndrome; and HALLUCINATIONS; PSYCHOSES; SEIZURES; and COMA in central anticholinergic syndrome.
