Video Summary
Wolff-Parkinson-White pattern (WPW) is a congenital disorder, in which there is heart arrhythmia caused by an extra electrical conduction pathway, called the Bundle of Kent, connecting the atria and ventricles. This can cause the ventricles to contract earlier, leading to pre-excitation, a short PR interval with a delta wave, and QRS prolongation on an electrocardiogram. While WPW is usually benign, it can lead to dangerous arrhythmias, such as atrioventricular reentrant tachycardia (AVRT), which can cause sudden cardiac death.
