Symptoms

By Mayo Clinic staff

Wolff-Parkinson-White syndrome symptoms are the result of a fast heart rate. Common signs and symptoms include:

  • Sensation of rapid, fluttering or pounding heartbeats (palpitations)
  • Dizziness
  • Lightheadedness
  • Fainting
  • Easily tired during exercise
  • Anxiety

Symptoms most often appear for the first time in people in their teens or 20s. An episode of a very fast heartbeat can begin suddenly and last for a few seconds or several hours. Episodes often happen during exercise.

Symptoms in more serious cases
If a person with Wolff-Parkinson-White syndrome also has underlying heart disease, a rapid heart rate can lead to other serious symptoms, including:

  • Chest pain
  • Chest tightness
  • Difficulty breathing
  • Sudden death

Symptoms in infants
Symptoms in infants with Wolff-Parkinson-White syndrome may include:

  • Shortness of breath
  • Not alert or active
  • Poor eating
  • Fast heartbeats visible on the chest

No symptoms
A person may have an extra electrical pathway in the heart but experience no fast heartbeat and no symptoms. This condition, called Wolff-Parkinson-White pattern, is only discovered by chance when a person is undergoing a heart exam for other reasons.

When to see a doctor
A number of conditions can cause irregular heartbeats (arrhythmia). It's important to get a prompt, accurate diagnosis and appropriate care. See your doctor if you or your child experiences any symptoms associated with Wolff-Parkinson-White syndrome. If you faint, have difficulty breathing or have chest pain lasting more than a few minutes, get emergency care or call 911 or your local emergency number.
