Abstract
A 64-year-old female with Wolff-Parkinson-White syndrome and an ECG demonstrating a rigbt posterolateral accessory pathway was referred for electrophysiological study. During electrophysiological testing two AV pathways were identified: a right posterolateral pathway that displayed conventional electrophysiological properties: and a left free-wall pathway tbat conducted only anterogradely and demonstrated decremental properties. Two separate wide complex tachycardias were induced that utilized the left free-wall pathway anterogradely and either the AV node or the right posterolateral accessory pathway retrogradely. A discrete electrical potential on the free wall of the mitral an-nulus was identified during tachycardia and was utilized to facilitate mapping and ablation.
