Wolff-Parkinson-White Syndrome WPW is a congenital abnormality characterized by an abnormal accessory conduction pathway between the atria and the ventricle known as the bundle of kent. Look out for a delta wave, short PR, and widened QRS interval on EKG. The definitive treatment is ablation. 1 Slurred upstroke of QRS complex (Delta wave) 2 Wide QRS complex (QRS > 120 msec) 3 Short PR interval (PR < 120 msec) #WolffParkinsonWhite #WPW #Cardiology #ECG #EKG #Electrocardiogram #Clinical #Diagnosis
