Wolff-Parkinson-White syndrome, also known as WPW syndrome, is a condition that leads to tachycardia of the heart (fast heartbeat). There is an abnormal electrical pathway inside the heart that is the cause of this condition. WPW syndrome is congenital in nature, meaning that it is present since birth; however, the effects of a fast heartbeat may not show up until a person is in their teens or early 20's.

Symptoms of WPW syndrome include experiencing rapid heartbeats, dizziness, fainting and early fatigue during exercises. These symptoms can accompany an episode of a fast heartbeat, which can last for a few seconds to several hours. There are some individuals diagnosed with Wolff-Parkinson-White syndrome that also have heart disease. In these instances, when they experience rapid heartbeat, it may be accompanied with chest pain or tightness, breathing difficulties or even death. If this condition is present in infants, look for signs that include shortness of breath, not eating and fast heart palpitations visible on the chest. In some cases, a person may show no signs or symptoms of a fast heartbeat, despite having an additional electrical pathway inside the heart. For these individuals, the diagnosis of WPW syndrome is revealed through chance when the person undergoes a heart exam for other reasons.

Although most cases of WPW syndrome are not considered life-threatening, there are instances in which serious heart problems can arise. Treatment for this condition may include medication to slow down the heart rate. Your physician may also have you perform what is called a "vagal maneuver," which will help regulate the heart rate. For others, surgery may also be the best option in order to correct any further heartbeat problems.

Individuals with Wolff-Parkinson's-White syndrome should also avoid caffeine, alcohol and tobacco products, as these substances will contribute to a faster heartbeat.
