The characteristic [[EKG]] finding is a [[delta wave]], which represents the pre-excitation of the [[ventricles]] through the [[accessory pathway]].

Overview

The diagnose of WPW pattern is commonly made by an incidental ECG finding in an asymptomatic individuals. The characteristic EKG finding is a delta wave, which represents the pre-excitation of the ventricles through the accessory pathway. This phenomenon presents because the AV node has the property of slowing the impulses, therefore the conduction through the accessory pathway is faster, therefore the ventricles are excited through two different pathways. The delta wave is an upstroke in the R wave of the QRS complex that is associated with a short PR interval. Delta waves are only present when the patient is in sinus rhythm, whentachycardia starts the delta wave is no longer present. Patients WPW syndrome with episodes of atrial fibrillation will present ECG with rapid irregular wide-complex tachycardia. The combination of atrial fibrillation and WPW may increase the risk of very rapid antidromic AVRT and occurrence of ventricular fibrillation. AV node blocking agents are contraindicated in these patients because it will enhance the conduction through the accessory pathway. Patients with WPW may exhibit more than one accessory pathway which is common in patients with Ebstein's anomaly.
