Timing Markers Showing Pacemaker Behavior to Aid in the Follow‐Up of a Physiological Pacemaker

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.
