Lown-Ganong-Levine syndrome

In medicine, Lown-Ganong-Levine syndrome is "a form of ventricular pre-excitation characterized by a short PR interval and a normal QRS complex. In this syndrome, the atrial impulse conducts via the James fibers which connect the atrium to bundle of bundle of His bypassing the upper atrioventricular node. Heart ventricles are depolarized normally through the His-Purkinje system."
