An innovative application of anatomic electromagnetic voltage mapping in a patient with Ebstein's anomaly undergoing permanent pacemaker implantation.

abstract：INTRODUCTION:Phrenic nerve (PN) injury is a well-known complication of cryoballoon ablation (CBA) for pulmonary vein (PV) isolation in patients with atrial fibrillation. However, it is still insufficient to practically predict phrenic nerve injury (PNI) before freezing. We hypothesized that phrenic nerve capture (PNC) ...
