Key result
Pacemaker algorithms successfully diagnose and terminate PMT caused by inverted atrial and ventricular leads.
Device algorithms can successfully detect and terminate pacemaker-mediated tachycardia even in the unusual setting of inverted atrial and ventricular lead connections.
Device algorithms may resolve PMT despite lead inversion; leaves open need for verification protocols in larger series.
Inverted connection of the atrial and ventricular leads is an unusual circumstance during the implantation of a dual-chamber pacemaker. Yet, PMT may present in the absence of complex mechanisms. The detection and termination algorithms used by the device proved to be efficient for the adequate diagnosis and treatment.
