What is POTS, a extensive explanation.
Update: Postural Orthostatic Tachycardia Syndrome (POTS) Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system, which regulates involuntary functions such as heart rate, blood pressure, circulation, and digestion. It is characterized by orthostatic intolerance and an excessive increase in heart rate after moving to an upright position, often accompanied by disabling multisystem symptoms. POTS and Long COVID Long COVID is associated with persistent autonomic dysfunction, including orthostatic intolerance and POTS. In a cross-sectional study of individuals with symptoms lasting at least four weeks after moderate COVID-19, beat-to-beat cardiovascular recordings and a novel geometric method were used to characterize baroreflex sensitivity (BRS). During orthostasis, patients exhibited significantly lower BRS than healthy controls. Reduced BRS was associated with higher arterial blood pressure and heart rate, as well as lower heart-rate variabilit...
