A systematic examination of the potential hazards of electromagnetic interference with pacemakers in patients in the dental environment was carried out with the use of several pulse generators of three manufacturers. Only one model was affected by the dental operatory equipment tested. In two of three patients 2-second periods of asystole were noted: this was accompanied by symptoms in one. Permanent pacemakers implanted in three dogs were unaffected by short or sustained stimulation with pulp vitality testers. A permanent pacemaker implanted in one dog was unaffected by short or sustained stimulation with an ultrasonic cleaner. Reliance on severe symptoms alone is a poor method of assessing interference in the clinical situation. Guidelines for protection of the patient wearing a pacemaker in the dental environment are given.
使用三个制造商生产的几种脉冲发生器，对牙科环境中患者起搏器受电磁干扰的潜在危害进行了系统检查。测试的牙科诊疗设备仅对一种型号产生影响。在三名患者中有两名出现了2秒的心脏停搏期：其中一名伴有症状。植入三只狗体内的永久起搏器未受牙髓活力测试仪短时间或持续刺激的影响。植入一只狗体内的永久起搏器未受超声波清洁器短时间或持续刺激的影响。仅依靠严重症状来评估临床情况下的干扰是一种欠佳的方法。文中给出了在牙科环境中保护佩戴起搏器患者的指导原则。
