POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME

Dizzy when you stand,
and your heart races?

Postural orthostatic tachycardia syndrome (POTS) is evaluated by looking at the rise in heart rate on standing together with persistent orthostatic symptoms. Blood pressure response and other possible causes also need to be checked.

Symptoms that suggest POTS

Palpitations, dizziness, fatigue, or difficulty concentrating while standing that improve when lying down are clues for evaluation. Symptoms alone cannot confirm the diagnosis.

What we check at the visit

  1. When symptoms began and how they relate to standing, heat, meals, and activity
  2. Changes in blood pressure and pulse over time while lying down and after standing
  3. Medications and other possible causes such as dehydration, anemia, or thyroid disease
  4. Tilt-table testing and further evaluation when needed

Treatment and follow-up

Based on the diagnosis and any coexisting conditions, we consider lifestyle adjustments and, where needed, medication. We look not only at pulse numbers but also at changes in daily function such as standing, commuting, and studying.

Treatment choices and exercise intensity differ from patient to patient. In particular, if your symptoms worsen with a delay after activity, please tell us about this pattern first.

FAQ

Can I bring my smartwatch records?

Yes. Noting the time and your posture when symptoms occurred is helpful. However, heart rate from a wrist device alone cannot be used to make a diagnosis.

Do you evaluate palpitations that started after COVID-19?

Orthostatic symptoms can begin after an infection. Not every case of palpitations is POTS, so we review how symptoms developed, how they change on standing, and whether other cardiac or systemic causes are possible.
