Patients with 41 implanted non-competitive pacemakers were investigated. A variety of domestic electrical equipment, a motor-car, and a physiotherapy diathermy apparatus were each operated in turn at various ranges from the patient. Interference effects on pacemaker function were assessed on the electrocardiograph. Medtronic demand 5841 pacemakers were stopped by diathermy while Cordis Ectocor pacemakers developed a fast discharge rate. Cordis triggered pacemakers (both Atricor and Ectocor) were sensitive to interference from many items of domestic equipment and the motor car. The Elema EM153 ran at an increased rate when an electric razor was running close to the pacemaker. The Devices demand 2980 and the Medtronic demand 5841 were not affected by the domestic equipment tested. The significance of interference effects is discussed in relation to pacemaker design.
对41名植入非竞争性起搏器的患者进行了调查。依次让患者处于不同距离操作各种家用电气设备、一辆汽车和一台理疗透热疗法仪器。通过心电图评估对起搏器功能的干扰影响。美敦力按需型5841起搏器在透热疗法时停止工作，而科迪斯外心起搏器的放电速率加快。科迪斯触发型起搏器（心房触发型和外心触发型）对许多家用设备和汽车产生的干扰敏感。当电动剃须刀在靠近起搏器的位置运行时，伊莱玛EM153起搏器的运行速率增加。所测试的家用设备对德维茨按需型2980起搏器和美敦力按需型5841起搏器没有影响。结合起搏器设计讨论了干扰影响的重要性。
