Postural Orthostatic Tachycardia Syndrome (POTS)


Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally rapid increase in heart rate upon standing up from a sitting or lying position. This can lead to symptoms such as dizziness, lightheadedness, and fainting. POTS is often caused by dysfunction in the autonomic nervous system, which regulates involuntary body functions like heart rate and blood pressure.
