Wolff-Par·kin·son-White syn·drome

(wūlf park'in-son wīt), [MIM*194200]
an electrocardiographic pattern sometimes associated with paroxysmal tachycardia; it consists of a short PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).

Wolff-Par·kin·son-White syn·drome

(wūlf park'in-son wīt), [MIM*194200]
an electrocardiographic pattern sometimes associated with paroxysmal tachycardia; it consists of a short PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).
A cardiac conduction disorder in which the sinoatrial impulse travels directly to the AV node or anomalously via the more rapid Kent’s bundle, resulting in premature ventricular contractions and increased susceptibility to supraventricular paroxysmal tachyarrhythmias
EKG Short PR interval—< 0.1 sec—a slur on the upstroke of the R or on the downstroke of an S wave or delta wave, prolonged QRS complex, often ST-T changes
Management Cardioversion, procainamide, lidocaine or radiofrequency ablation of accessory AV pathway
