Electrical cardioversion or defibrillation may be necessary in patients with implanted artificial cardiac pacemakers. Sudden discharge of high electrical energy employed in DC transthoracic countershock procedures may damage the sensitive pacemaker circuitry and result in malfunction. We report a case in which, following synchronized DC countershock, a non-programmable demand pacemaker functioned in the R-wave triggered mode rather than the R-wave inhibited mode as designed. Further, the pacemaker output voltage was reduced to about half its specified output. Such a malfunction may not be readily apparent, and requires careful analysis following electric shock.
对于植入人工心脏起搏器的患者，可能需要进行电复律或除颤。直流经胸除颤程序中使用的高电能突然放电可能会损坏敏感的起搏器电路并导致故障。我们报告了一例病例，在同步直流除颤后，一个非程控按需起搏器以R波触发模式而非设计的R波抑制模式工作。此外，起搏器输出电压降至其规定输出的约一半。这种故障可能不容易显现，电击后需要仔细分析。
