The beneficial effect of permanenl pacing is controversial in certain patient groups. Once pacing has been instituted it isseldom terminated and an evaluation of pacemaker depen‘dence is therefore not possible. An implantable puise generator, detecting bradycardia beiow 30 bpm has beendeveiopedin order tobroaden ourknowledgeabout the natural history of bradyarrhythmias treated by permanent pacing. This pacemaker has been implanted in 30 patients who did not have clear‐cut indications for permanent pacing. They have been followed for a mean of 13 months. Bradycardia was detected in 33 patients 1 to 21 months (4.6 mean) affer implantation. Twenty‐one patients did not have a defected bradycardia for Jong periods (months‐years). Minor symptoms of lightheadedness a dributable to bradycardia were reported by 15 patients during periods when the pacemaker had been activated. Holter monitoring for at least 24 hours was carried out in all patienls and electronic analysis of explanted generalors was performed in eieven cases. No tecnnical failure relaled to the bradycardia‐detecting facility was observed. The combination of diagnostic and therapeutic properties in the bradycardia‐indicating pacemaker provides means for safe evaluation of pacemaker dependency over long time periods in patienl groups with controversial indications for permanent pacing.
