Multiple Choice

The bundle of Kent is best described as which of the following?

The bundle of Kent is an accessory conduction pathway that runs from the atria to the ventricles, bypassing the AV node. In conditions like Wolff-Parkinson-White syndrome, this pre-existing pathway allows impulses to reach the ventricles earlier than the normal route, causing pre-excitation of the ventricles. This can show up on ECG as a short PR interval with a delta wave and can predispose to re-entrant tachycardias. It is not the normal AV nodal pathway, not the sinoatrial node, and not the Purkinje network.
