FIGURE 17-8. Reentry mechanism for AV-accessory-pathway PSVT in Wolff-Parkinson-White syndrome. A. Sinus rhythm. The impulse travels from the atrium to the ventricle by two pathways—the AV node and an accessory bypass pathway. B. AV reentry. A critically timed premature impulse ( ) is stopped in the Kent bundle (because of prolonged refractoriness) but travels antegrade through the AV node and retrograde through the Kent bundle.

Supravantricular tachycardia is classified into several types depending on the localization of the reentrant circuit. The most common type is AV reentrant tachycardia via an accessory pathway (i.e., the bundle of Kent). The main objective of therapy is... 

Named after the discoverers of the syndrome, WPW is caused by a foetal abnormality resulting in an additional pathway between the atria and the ventricles. As discussed earlier the atria and ventricles are electrically isolated by the atrioventricular ring. Electrical impulses pass from atria to ventricle by the AV node and the His bundle into the ventricles, hi WPW an extra accessory pathway exists between the atria and ventricles (Fig. 6.26). This pathway is called the Brmdle of Kent . The electrical impulse can now travel through the AV node in the normal way and through the accessory pathway. 

WPW syndrome is clinically significant because the accessory pathway-in this case, Kent s bundle-may result in paroxysmal tachyarrhythmias by reentry and rapid conduction mecha-...
