[Malfunctions of pacemakers].
No pacemaker is absolutely reliable : more or less threatening failures can be observed after implantation. Pacemaker runaway has completely disappeared. Sudden battery failure, intermittent or permanent, remains too frequent. Other incidents, less frequent or severe, are also reviewed. Failures are often isolated and sporadic, but can sometimes involve a complete manufacture series. It is a medical duty  to follow-up carefully the patients and to announce the failures with a view to permit early recognition of imperfect series. Pacing failures do not play a major role in the mortality in the group of patients with permanently implanted pacemakers. Nevertheless, anticipated replacement of pacemakers increases the cost of the technique.
