title: Timing markers showing pacemaker behavior to aid in the follow-up of a physiological pacemaker.
abstract: In the present study a multiprogrammable, atrial synchronous, ventricular inhibited pacemaker (Enertrax) was used in six patients. This pacer makes it possible to evaluate pacemaker performance non-invasively and facilitates the correct interpretation of the difficult ECGs produced by these complex pacemakers.
