The influence of radiotherapy on 19 new, modern pacemakers has been determined. Seven pacemakers lost output at 120 Gy. Eight pacemakers showed inhibitions during irradiation in the direct beam. Five pacemakers did not show any malfunction at all. Most malfunctions were observed at dose levels exceeding 20 Gy. Although the newest generation of pacemakers exhibit a variety of defects, AAPM taskgroup 34 guidelines still seem to be valid.
已确定放射治疗对19个新型现代起搏器的影响。7个起搏器在120戈瑞时失去输出。8个起搏器在直接射束照射期间出现抑制现象。5个起搏器根本未出现任何故障。大多数故障出现在剂量超过20戈瑞时。尽管最新一代起搏器存在各种缺陷，但美国医学物理学家协会任务组34指南似乎仍然有效。
