![]() ![]() During tachycardia, the patient is cool, diaphoretic, and hypotensive.Evidence of congestive heart failure if the episode has been untreated for several hours.It can also trigger ventricular fibrillation which can be life-threatening, although this is extremely rare. ![]() This may result in syncope or cause sudden death. They can also have atrial fibrillation or atrial flutter resulting in a heartbeat crossing more than 250 to 300 times per minute. The most commonly found symptoms of WPW syndrome include:Ī person with WPW can have a heart rate of 160 to 220 beats per minute. It can be triggered by caffeine or other stimulants including alcohol. The episode can occur during exercise or while at rest and may last for a few seconds or several hours. The symptoms may come as an episode of rapid heartbeat that may begin suddenly. Although the symptoms most often appear for the first time in teenagers, people of all ages, including infants, can experience its symptoms. Most people with WPF usually do not feel any fast heartbeat. Symptoms of Wolff-Parkinson-White (WPW) syndrome It is also associated with some forms of congenital heart disease, such as Ebstein’s anomaly. Cause of WPW syndromeĪlthough there is no exact cause known for the development of extra pathways, an abnormal gene is found to be the cause of WPW in a small percentage of people. That is why further evaluation is recommended before children with WPW patterns participate in high-intensity sports. The disorder is usually not life-threatening but can cause serious heart problems. WPW is a type of supraventricular tachycardia called atrioventricular reciprocating tachycardia (AVRT). The extra electrical pathway is called a bypass tract as it bypasses the AV node and it could not control the heartbeat making it beat very fast. This occurs due to an abnormal alternate electrical pathway (accessory pathway) between the atrium and the ventricle of the heart. Wolff-Parkinson-White (WPW) syndrome is a very rare congenital heart disorder that causes abnormal heartbeat rhythms (arrhythmias) and faster than normal heartbeats (tachycardia). ![]()
