Postural orthostatic tachycardia syndrome (POTS) is a fast heart rate (tachycardia) that starts after you stand up. This can cause symptoms such as dizziness or weakness.
With POTS, the body does not control the heart rate as it should after you stand up. The change in heart rate happens within 10 minutes of standing up. This leads to symptoms such as dizziness, trembling, or weakness. You might have a fast heart rate (palpitations).
What are the symptoms?
Soon after you stand up, you may have symptoms such as:
A fast, pounding heartbeat (palpitations).
Trembling, dizziness, weakness, or lightheadedness.
Feeling faint or very tired.
With POTS, you may also have problems with:
Blurred vision, headaches, nausea, and diarrhea.
Trouble sleeping and feeling anxious.
Keeping your attention focused.
Symptoms can range from mild to severe.
Some things can make symptoms worse. These include heat, menstrual cycle, dehydration, alcohol, exercise, and standing for a long time.
When you first notice symptoms, lying down may help you feel better.
Experts don't understand what causes it, but different body systems seem to be out of balance. POTS may follow certain triggers such as a viral illness, a surgery, or pregnancy.
Your doctor may ask about your symptoms, including when and how they started. Your doctor may check how your blood pressure and heart rate change when you move from lying down to sitting to standing. They may do a tilt table test and blood tests. They may check your heart with an electrocardiogram (EKG).
Work with your doctor to find the right mix of treatments to help relieve symptoms and improve your quality of life. Treatment may include taking medicine prescribed by your doctor. For some people, taking medicine that affects blood pressure can help. Taking medicine that keeps the body's fluids balanced may also help.
Call 911 anytime you think you may need emergency care. For example, call if:
You passed out (lost consciousness), and it feels different than your typical episode or you don't recover as quickly as you have in the past.
Call your doctor now or seek immediate medical care if:
Your symptoms are getting worse. For example, you are more dizzy or lightheaded.
Watch closely for changes in your health, and be sure to contact your doctor if:
You do not get better as expected.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
