POTS meaning in Medical ?

Postural orthostatic tachycardia syndrome (POTS) is a condition in which a change from lying to standing causes an abnormally large (or higher than normal) increase in heart beat rate. This occurs with symptoms that may include lightheadedness, trouble thinking, blurred vision, or weakness. Other commonly associated conditions include Ehlers–Danlos syndrome, mast cell activation syndrome, irritable bowel syndrome, insomnia, chronic headaches, chronic fatigue syndrome, and fibromyalgia. It can be treated with lifestyle changes such as increasing fluid and salt intake, compression stockings, rising slowly after lying down, avoiding prolonged bedrest, and medication.
