Wolff-Parkinson-White Syndrome
Alternate Names : Pre-Excitation Syndrome
How is the disease diagnosed?
An electrocardiogram (ECG), or graphic recording of the electrical activity of the heart, is used to diagnose this problem. If the abnormal rhythm is present, the individual will have a heart rate of between 120 and 200 beats per minute. If the tachycadia is not occurring while the person is being examined, he or she will appear normal. An ECG is usually abnormal even in the absence of symptoms.
A more specialized test, known as an electrophysiology study, can also be performed. This test involves placing a catheter, or thin tube, through the skin and into an artery in the groin. The catheter is then advanced into the heart to map its electrical activity. This technique can be used to both diagnose and treat the disorder.
