Abstract

Abstract: A 47‐year‐old woman with Ebstein's anomaly suffered from an out‐of‐hospital cardiac arrest caused by ventricular fibrillation. Electroanatomical activation mapping showed an atrialized right ventricle. Atrial electrocardiogram, normal atrioventricular node conduction delay, and ventricular electrocardiogram were confirmed in the right atrium. Relatively preserved ventricular amplitude was found in the septal wall. Based on these findings, a transvenous dual‐chamber implantable cardioverter‐defibrillator was implanted for the prevention of sudden cardiac death. The patient has fared well, without any lead malfunctions, lead dislodgement, or inappropriate shocks. Sufficiently high atrial and ventricular amplitudes were confirmed during 18 months of follow‐up.
