Lown-Ganong-Levine Syndrome

Electrocardiographic syndrome of a short PR interval with normal duration of the QRS complex; it lacks the slurred delta wave of the Wolff-Parkinson-White syndrome, but resembles it in its frequent (controversial) association with paroxysmal tachycardia which qualifies it as a syndrome; otherwise short PR may occur in otherwise normal individuals.
