Abstract
The authors present a case of radiation-induced pacemaker failure. After 2,000 rad (20 Gy) of photon irradiation for metastatic bronchogenic carcinoma, the pulse generator circuitry failed, producing a "runaway" rhythm. This suggests that present pacemaker circuitry may be more susceptible to irradiation than previously believed, and that even modest radiation doses can induce life-threatening arrhythmias.
摘要
作者报告了一例放射性起搏器故障病例。在对转移性支气管癌进行2000拉德（20戈瑞）的光子照射后，脉冲发生器电路发生故障，产生了“失控”节律。这表明目前的起搏器电路可能比以前认为的更容易受到辐射影响，而且即使是适度的辐射剂量也可能诱发危及生命的心律失常。
