Leadless cardiac pacemakers such as the Micra transcatheter leadless pacing system provide an alternative to traditional transvenous pacemakers. Implantation of leadless pacemakers, albeit safe may be associated with complications including cardiac tamponade, high capture thresholds, and rarely, ventricular arrhythmias. We report a case of ventricular fibrillation arrest following Micra leadless pacemaker implantation.
