for bdj

66. The answer is E. (Wolff-Parkinson-White syndrome) The two major features of Wolff-Parkinson-White Syndrome (WPW) include a short PR interval (<0.12 second) and a delta wave. The QRS is wide (>0.12 second) and is considered a fusion beat. The initial part of the delta wave results from rapid depolarization of the accessory pathway. Termination of ventricular depolarization is through the normal activation pathway and gives rise to a normal appearing terminal portion of the QRS complex.
