Multiprogrammable pacemakers, using complimentary metaloxide semiconductor (CMOS) circuitry, may fail during radiation therapy. We report about a patient who received 6,400 cGy for unresectable carcinoma of the left lung. In supine treatment position, arms raised above the head, the pacemaker was outside the treated area by a margin of at least 1 cm, shielded by cerrobend blocking mounted on a tray. From thermoluminescent dosimeter (TLD) measurements, we estimate that the pacemaker received 620 cGy in scatter doses. Its function was monitored before, during, and after completion of radiation therapy. The pacemaker was functioning normally until the patient's death 5 months after completion of treatment. The relevant electrocardiograms (ECGs) are presented.
使用互补金属氧化物半导体（CMOS）电路的多程控起搏器在放射治疗期间可能会出现故障。我们报告了一名因左肺不可切除癌接受6400 cGy照射的患者。在仰卧治疗体位、双臂举过头顶时，起搏器位于治疗区域外至少1厘米处，由安装在托盘上的铈棒遮挡物屏蔽。根据热释光剂量计（TLD）测量，我们估计起搏器在散射剂量下接受了620 cGy的照射。在放射治疗开始前、期间和结束后对其功能进行了监测。直到治疗结束5个月后患者死亡，起搏器功能一直正常。文中给出了相关心电图（ECG）。
