A 48-year-old white man with a multiprogrammable Intramedics 259-01 pacemaker was treated for inoperable lung cancer with a course of cobalt-60 radiotherapy (total 3,500 rad). Several weeks subsequent to his last radiation treatment, the patient presented to the emergency department with chest and abdominal pain, shortness of breath, hypotension, and tachycardia. A paced tachycardia was noted, and application of a magnet over the pacemaker completely inhibited its function, allowing a normal sinus rhythm to ensue and the patient's symptoms to be relieved. Pacemaker failure probably was a complication of radiotherapy.
一名48岁的白人男性,植入了可程控的Intramedics 259 - 01型起搏器,因无法手术的肺癌接受了一个疗程的钴-60放射治疗(总计3500拉德)。在他最后一次放疗后的几周,患者因胸痛、腹痛、呼吸急促、低血压和心动过速被送往急诊科。发现有起搏性心动过速,在起搏器上放置一块磁铁后完全抑制了其功能,使正常窦性心律出现,患者症状得到缓解。起搏器故障可能是放射治疗的一个并发症。
