Magnetic navigation and voltage mapping guided implantation of a pacemaker atrial lead in a previously unpaceable patient.

We report successful implantation of the atrial pacing lead in a patient in whom such operation had previously failed with the manual approach. Right atrial (RA) electro-anatomical voltage mapping was used to identify an area suitable for pacing and magnetic navigation to allow exhaustive RA exploration leading to successful RA lead screwing.
