Waardenburg syndrome is most often inherited as an trait. This means only one parent has to pass on the faulty gene for a child to be affected. There are four main types of Waardenburg syndrome. Waardenburg syndrome is a genetic disorder characterized by patchy areas of depigmentation of the skin and hair. One type of Waardenburg syndrome also produces congenital deafness (deaf at birth). This disorder is believed to account for 2-3% of all cases of congenital deafness. The most common are type I and type II. Type III (Klein-Waardenburg syndrome) and type IV (Waardenburg-Shah syndrome) are rarer. The multiple types of this syndrome result from defects in different genes. Most people with this disease have a parent with the disease, but the symptoms in the parent can be quite different from those in the child. A.D.A.M., Inc.

Diagnosis Your doctor will likely recommend heart tests to diagnose WPW syndrome, such as: • Electrocardiogram (ECG). Small sensors attached to your chest and arms record electrical signals as they travel through your heart. Your doctor can look for patterns among these signals that indicate the presence of an extra electrical pathway in your heart. • Portable ECG. Using a portable ECG device at home provides more information about your heart rate. A Holter monitor records your heart activity for 24 hours. An event recorder monitors heart activity when you experience symptoms of a fast heart rate. • Electrophysiological testing. Thin, flexible tubes (catheters) tipped with electrodes are threaded through your blood vessels to various spots in your heart. The electrodes can precisely map the spread of electrical impulses during each heartbeat and identify an extra electrical pathway. Cardiac catheter ablation In catheter ablation, catheters are threaded through the blood vessels to the inner heart, and electrodes at the catheter tips map the spread of electrical impulses through the heart. Electrodes at the catheter tips transmit energy to destroy a small spot of heart tissue and create an electrical block along the pathway that's causing your arrhythmia. Treatment depends on several factors, including the severity and frequency of your symptoms. If you have the WPW pathway but don't have any symptoms, you probably won't need treatment. If treatment is needed, the goal is to slow a fast heart rate when it occurs and to prevent future episodes. Treatment options include: • Vagal maneuvers. These simple physical movements — which include coughing, bearing down as if you are having a bowel movement and putting an ice pack on your face — affect a nerve that helps regulate your heartbeat (vagus nerve). Your doctor may recommend performing vagal maneuvers to help slow a rapid heartbeat when it occurs. • Medications. If vagal maneuvers don't stop the fast heartbeat, you may need an injection of an anti-arrhythmic medication.
