Key result
The typical electrocardiographic features of Wolff-Parkinson-White pattern include a short PR interval of less than 120 ms, QRS prolongation usually greater than 110 ms, and a delta wave.
Why the study?
It is important to recognize the common electrocardiographic characteristics of Wolff-Parkinson-White pattern, which may predispose symptomatic patients to arrhythmias and sudden cardiac death.

This review summarizes the electrocardiographic features, types, mimics, and clinical implications of the Wolff-Parkinson-White pattern and syndrome.
Electrocardiographic features of a short PR interval, a delta wave, and a wide QRS complex constitutes a Wolff-Parkinson-White (WPW) pattern.Asymptomatic electrocardiographic findings are defined as a WPW pattern.Symptomatic patients with these electrocardiographic features have WPW syndrome.WPW syndrome may predispose to arrhythmias such as paroxysmal atrial tachycardia, atrial fibrillation, ventricular tachycardia.Patient's with WPW syndrome at risk for sudden cardiac death.It is important to recognize the common electrocardiographic characteristics of WPW pattern.The advent of electrophysiological studies (EPS) and radiofrequency ablation has revolutionized the management of WPW syndrome.
