Wolff-Parkinson-White (WPW) Syndrome is a genetic heart condition where there is an extra electrical pathway (circuit) in the heart; leading to abnormal conduction of electrical impulse from the atrial to the ventricles, causing episodes of rapid heart rate. While WPW Syndrome does not cause significant problems for most people, in some patients, it can lead to serious heart conditions like tachyarrhythmias and sudden cardiac death.
