“According to the NHS: “Postural tachycardia syndrome (PoTS) is when your heart rate increases very quickly after getting up from sitting or lying down. It can get better with changes to your lifestyle, but some people may need treatment with medicines.” The condition is also sometimes known as postural orthostatic tachycardia syndrome. In recent years, cases of the condition have risen and interest in it has, too, with Google Trends data showing that even just in the past year, there has been a 61% increase in people searching for the term.”
