What Is Paroxysmal Supraventricular Tachycardia?

During paroxysmal supraventricular tachycardia, you experience sudden, reoccurring episodes of an abnormally fast heart rate (160 to 220 beats per minute). Short circuits or electrically irritable areas above the ventricles (lower chambers) of your heart cause the condition.

PSVT also may occur with Wolff-Parkinson-White syndrome—a genetic condition that involves an extra electrical pathway in the heart.

Symptoms of PSVT

With PSVT, your heart rate may speed up for a just a few minutes or for several hours. During this time, you may experience:

  • The feeling that your heart is beating too quickly or too hard (heart palpitations)
  • Weakness, dizziness or light-headedness
  • Chest pain or tightness
  • Shortness of breath
  • Anxiety

Types of PSVT

Count on Overlake Medical Center for expert treatment of all types of supraventricular tachycardia, including:

How Is PSVT Diagnosed?

If your physician thinks you have PSVT, you may be asked to wear an event monitor, such as a Holter monitor, to record your heartbeat for several days or weeks. This allows us to capture important information about your irregular heartbeat as you experience it.

Treatment Options for PSVT

You and your physician will work together to create a care plan that fits you and your condition.

For mild PSVT, you may be able to manage your arrhythmia through lifestyle changes and by learning techniques to stop a rapid heart rate.

For severe symptoms or long-lasting episodes, your physician may recommend prescription medications or catheter ablation—a minimally invasive procedure that stops abnormal electrical signals by eliminating small amounts of tissue in your heart.
