Postural tachycardia syndrome (PoTS) is a medical condition that causes an abnormal increase in heart rate that occurs after sitting up or standing/). It can develop suddenly or gradually over time, and some people have mild symptoms, while for others it can have a big impact on their everyday lives. Symptoms of PoTS include dizziness, lightheadedness, fainting, rapid heartbeat, and fatigue. These symptoms can be caused by other conditions, such as low blood pressure, so having them does not mean you definitely have PoTS.

If you have symptoms of PoTS, a GP may check your blood pressure and heart rate before and after you stand up. If they think you may have PoTS, theyll refer you to a specialist who may perform more tests, such as blood tests, pee (urine) tests, heart and blood pressure tests, such as an echocardiogram, ECG, and 24-hour blood pressure and heart rate monitoring. It can take time for people to be diagnosed with PoTS, as the symptoms are similar to other conditions.

Treatment for PoTS can take time, and a specialist may suggest making changes to your lifestyle, such as increasing salt and fluid intake, wearing compression stockings, and avoiding triggers that can make symptoms worse. Medications such as beta-blockers, fludrocortisone, and midodrine may also be prescribed.

If you have symptoms of PoTS, a GP may check your blood pressure and heart rate before and after you stand up and refer you to a specialist who may perform more tests.
