Kent bundle [Albert F.S. Kent, English physiologist, 1863–1958; AS, byndel, to bind] , an accessory pathway between an atrium and a ventricle outside the conduction system. This congenital anomaly causes Wolff-Parkinson-White syndrome. The term “accessory pathway” is preferred because the one Kent described had a precise location (anterior and near the fibrous ring of the tricuspid valve). See also Wolff-Parkinson-White syndrome.
