Wolf-Parkinson-White (WPW) syndrome is a name for a specific type of electrocardiographic finding that occurs due to the presence of an additional conduction pathway within the heart called a
Kent bundle. When electricity goes down the
Kent bundle, it results in the characteristic appearance on the electrocardiogram (ECG) called a delta wave. In many patients with WPW, a rapid heart rate called supraventricular tachycardia (SVT) may occur.
