Abstract

Abstract: A 26‐year‐old patient with prior surgery for Ebstein's anomaly and a pacemaker (placed for post‐surgical heart block and poor underlying rhythm) underwent SICD was placement. During defibrillation testing, device‐device interaction led to undersensing of ventricular fibrillation with failure to shock. Increasing the pacemaker sensitivity resolved the problem but post shock pacing was unable to capture the heart after both shocks. The patient underwent removal of both the pacemaker and the SICD and placement of a transvenous ICD. Complex device‐device interactions can occur in patients who are pacemaker dependent and undergo placement of a SICD.
