-
Lown-Ganong-Levine Syndrome. Electrocardiogram demonstrating a short PR interval of approximately 100 ms and normal QRS.
-
Lown-Ganong-Levine Syndrome. This electrocardiogram (ECG) demonstrates ventricular preexcitation. A delta wave, which corresponds to initial myocardial depolarization via a bypass tract, appears at the beginning of each QRS complex. Note: Although it is a common practice to label ECGs with manifest delta waves as Wolff-Parkinson-White syndrome (WPW), WPW is a clinical diagnosis that requires tachycardia in addition to ventricular preexcitation.
