Lown-Ganong-Levine Syndrome. by Chris Nickson, Last updated January 2, OVERVIEW. bypass close to the AV node connecting the left atrium and the. However, most lack the histopathologic correlation that has been demonstrated for the WPW syndrome. The Lown-Ganong-Levine (LGL). Background: Lown-Ganong-Levine syndrome, includes a short PR interval, normal QRS complex, and paroxysmal tachycardia.

Diagnostic criteria include PR interval of no more than ms, normal QRS complex duration, and paroxysmal supraventricular tachycardia PSVT but not atrial fibrillation or flutter.

Discussion In this case, the clinical and electrophysiologic characteristics were consistent with a diagnosis of Lown-Ganong-Levine syndrome, with a short PR interval, normal QRS complex, without a delta wave, and paroxysmal tachycardia.

Lown–Ganong–Levine syndrome

According to the experience gained, we suggest that TIVA with propofol through MCI regimen along with other short acting agents may be a good anaesthetic choice for such patients even in peripheral hospitals when general anaesthesia is required for major upper abdominal surgical procedures. On return of lveine spontaneous breathing efforts and airway reflexes, trachea was extubated.

Once thought to involve an accessory conduction pathway, it is grouped with Levin syndrome as an atrioventricular re-entrant tachycardia AVRT. In this case, since this pathway had some decremental properties, it is possible that the distal insertion site of this pathway was in the distal AV nodal area James fiber rather than connecting via the atria and the His bundle Brechenmacher fiber [ 34 ].


Unfortunately, this case showed no evidence of retrograde AV losn through the James fiber.

The James fiber in this patient appeared to be a bystander, which was not a tachycardia substrate. This article is for Medical Professionals. Lown Ganong Levine syndrome patients are prone to attacks of paroxysmal tachycardia specially supraventricular; however, occasional episodes of atrial fibrillation are usually of short duration and rarely sustained.

Therefore, lpwn pre-James fiber ablation curve was a hybrid of leine James fiber and a slow AV nodal pathway conduction curve; the post-James fiber ablation curve was a hybrid of fast and slow AV nodal conduction curve, and the post-slow pathway ablation curve was a hybrid of the James fiber and fast AV nodal conduction curve.

The findings in this case included an unusually short atrium to His AH conduction interval and a normal His to ventricle HV conduction interval without a delta wave; two different stable AH intervals coexisted at the same atrial pacing cycle length; and in the A1A2-A2H2 recovery curve study, this pathway had a flat conduction curve without AH increase until the last 60 ms before reaching its effective refractory period.

Comparison of the post-James fiber ablation recovery curve with that of the post-slow pathway gxnong curve with James fiber recurrence, it was noted that when the A1A2 was less than ms, the post-slow pathway ablation curve fast AV nodal conduction curve deviated downward from that of the pre-James fiber ablation curve slow pathway conduction curve.
