POTS is a form of dysautonomia — a disorder of the autonomic nervous system. This branch of the nervous system regulates functions we don’t consciously control, such as heart rate, blood pressure, sweating and body temperature. The key characteristics of POTS are the specific symptoms and the exaggerated increase in heart rate when standing.

When the autonomic nervous system malfunctions as it does in POTS, there is too much release of norepinephrine and epinephrine from the sympathetic nervous system and/or too little release of acetylcholine from the parasympathetic nervous system, causing these symptoms.

Autonomic influence on the Dura mater • Dense network of autonomic and sensory fibers within the Dura Mater • Parasympathetic stimulation (Carbachol) did not change levels of CGRP or PGE 2 • Sympathetic stimulation (Norepinephrine) show increased PGE 2 and reduced serotonin

Postural orthostatic tachycardia syndrome (POTS) is a common autonomic nervous system disorder characterized by an excessively fast heart rate and symptoms of lightheadedness upon standing.

Postural orthostatic tachycardia syndrome (POTS) is a type of dysautonomia, meaning a problem with the autonomic nervous system. Symptoms include lightheadedness, fainting, fatigue, and difficulty exercising. It can occur in both children and adults, and often begins in …

Dysfunction of the autonomic nervous system causes many different symptoms in people and may be called different names depending on those symptoms: orthostatic intolerance, POTS, neuro-cardiogenic syncope or dysautonomia.

Postural tachycardia syndrome (POTS)— POTS is not well understood, but is generally thought to be a problem with blood circulation that causes light-headedness, fainting, and an uncomfortable, rapid increase in heart rate.

Vague and common symptoms make disorders of the autonomic nervous system difficult to identify and treat, but better understanding among doctors is improving the prognosis for patients.

Postural orthostatic tachycardia syndrome (POTS) is the most common form of dysautonomia, characterized by malfunction of the autonomic nervous system. The range of potential symptoms of POTS is broad in both scope and severity.

Postural orthostatic tachycardia syndrome (POTS), a disorder of the autonomic nervous system characterized by a rise in heart rate of at least 30 bpm from supine to standing position, has been traditionally viewed as a dysfunction of the peripheral nervous system.
