Question

Quizplus · Accepted Answer

Wolff-Parkinson-White syndrome is caused by the presence of an accessory conduction pathway, which causes an abnormal widening of the QRS complex on an electrocardiogram. This pathway, called the bundle of Kent, allows electrical impulses to bypass the normal conduction pathway of the heart and can lead to reentry tachyarrhythmias.
