Electroanatomic localization of a slowly conducting atrioventricular (Mahaim) accessory pathway JOURNAL OF INTERVENTIONAL CARDIAC ELECTROPHYSIOLOGY Gupta, A., Hsia, H. H., Lo, R., Zei, P. C. 2011; 31 (2): 119-124

Abstract

We present a case of a 34-year-old female with Ebstein's anomaly and symptomatic wide complex tachyarrhythmia. Electrophysiologic evaluation demonstrated antidromic tachycardia utilizing a right-sided decremental, slowly conducting atrioventricular pathway. Distinct accessory pathway potentials along the length of the bypass tract were sequentially recorded to define the anatomic course of the pathway, as uniquely represented on a three-dimensional electroanatomic map, and to successfully guide catheter ablation.
