ELECTROPHYSIOLOGY
Better ventricular synchronization via an accessory pathway
Arrhythmia Unit, Department of Cardiology, Hospital Universitario La Paz, Madrid, Spain
We report of a patient in whom the presence of a left ventricular accessory pathway plus enhanced AV nodal conduction led to a more physiological ventricular activation sequence than that observed after ablation of the accessory pathway in a patient with baseline left bundle branch block and concealed intra-QRS pre-excitation.
Key Words: Electrocardiogram, Ablation, Bundle branch block
