Abstract
Anatomic Electromagnetic Voltage Mapping. A novel application of the Biosense CARTO System anatomic electromagnetic voltage mapping is presented, utilized as a guide for permanent pacemaker placement. The technique is illustrated in the successful implantation of an atrial lead in a patient with Ebstein's anomaly characterized by a severely dilated right atrium and extremely low‐amplitude voltage signals, requiring a DDD pacemaker. Electromagnetic voltage mapping can be used in selected patients with structural heart disease to determine the optimal site for permanent pacemaker lead placement.
