Nov 7, 2024 · Lown–Ganong–Levine syndrome (LGL): Proposed pre-excitation syndrome. Accessory pathway composed of James fibres. Characteristic ECG findings of short PR interval (<120ms); normal P wave axis; normal/narrow QRS morphology in the presence of paroxysmal tachyarrhythmia.

Lown–Ganong–Levine syndrome (LGL) is a pre-excitation syndrome of the heart. Those with LGL syndrome have episodes of abnormal heart racing with a short PR interval and normal QRS complexes seen on their electrocardiogram when in a normal sinus rhythm.

Oct 8, 2024 · This page covers the pathophysiology and ECG features of pre-excitation syndromes in sinus rhythm. The two main forms of tachyarrhythmias that occur due to accessory pathways are discussed separately — see atrioventricular re-entry tachycardia (AVRT) and atrial fibrillation/flutter in pre-excitation .

The Lown-Ganong-Levine (LGL) pattern is characterized by the presence of a short PR interval (120 milliseconds) and normal QRS complex on the surface ECG. This finding may represent a perinodal accessory pathway or enhanced AV nodal conduction ( waveform 1 ).

The Lown-Ganong-Levine syndrome (LGL) is a clinical syndrome consisting of paroxysms of tachycardia and electrocardiogram (ECG) findings of a short PR interval and normal QRS duration....

The Lown-Ganong-Levine (LGL) syndrome occurs when an accessory pathway is congenitally present that directly connects the atria to the ventricles, bypassing the AV node similar to the...

Lown-Ganong-Levine syndrome is an extremely rare conduction disorder characterized by a short PR interval (less than or equal to 120 ms) with normal QRS complex on electrocardiogram associated with the occurrence of episodes of atrial tachyarrythmias (e.g. atrial fibrillation, atrial tachycardia).

Learn about Lown-Ganong-Levine (LGL) Syndrome, its shortened PQ interval, accelerated AV conduction, and its implications on ECG readings.

Lown-Ganong-Levine syndrome is an extremely rare conduction disorder characterized by a short PR interval (less than or equal to 120 ms) with normal QRS complex on electrocardiogram associated with the occurrence of episodes of atrial tachyarrythmias (e.g. atrial fibrillation, atrial tachycardia).
