Kent's cluster

From WikiLectures


Kent's cluster is an additional (accessory, pathological) bundle of cardiac muscle connecting the heart's atria and ventricles. It is present, and congenital, only in a small number of people, in whom it is often the cause of premature activation of the heart chambers - preexcitation. Physiologically, the atria and ventricles are connected only by the bundle of His.

The most common ventricular preexcitation syndrome is Wolff–Parkinson–White syndrome – WPW. This is a cardiac arrhythmia in which the impulse (depolarization wave) spreads from the atria to the ventricles outside the AV node. The accessory track here is precisely Kent's cluster.
