Wolff-Parkinson-White syndrome

A person with WPW syndrome may have:

• palpitations (a sensation of feeling your heart beat)
• light-headedness
• fainting
• dizziness
• shortness of breath
• chest pain or chest tightness

An exam performed during a tachycardia episodewill reveal a heart rate greater than 150 (normal is 60 to 100 beats per minute), and blood pressure that is normal or low. If the patient is currently not havingtachycardia, the physical exam may be completely normal. Wolff-Parkinson-White syndrome may be revealed by the following tests:

• ECG (electrocardiogram), which looks for a finding called a "delta wave"
• Continuous ambulatory monitoring (Holter monitor), which may record an episode of arrhythmia
• EPS, an intracardiac electrophysiologic study
