Postural orthostatic tachycardia syndrome is a form of rapid heartbeat that occurs when an individual moves from a sitting or lying position to a standing position. It’s related to problems with blood flow and can cause lightheadedness or fainting among other symptoms.
The direct cause of postural orthostatic tachycardia syndrome is not enough blood returning to the heart when a person moves from sitting or lying to standing up. Why this occurs in some is unclear, however, it might be related to nerve, circulation or blood pressure issues, among others. Some people have a family history of the disease, while others do not.
