A 25-year-old woman with Wolff-Parkinson-White syndrome was referred for catheter ablation. The 12-lead EKG is consistent with an anteroseptal accessory pathway (AP) (Fig. 37.1). A previous attempt at ablation of the AP was aborted due to its proximity to the His bundle. Another attempt at ablation was made. The baseline rhythm was sinus with ventricular preexcitation. Orthodromic AVRT was inducible and the AP had a short refractory period that was less than 250 ms. The earliest ventricular activation during sinus rhythm was at a site where there was also a large His bundle recording during block in the AP. How would you proceed?
