A middle-aged gentleman with an idiopathic dilated cardiomyopathy, drug-refractory sustained ventricular arrhythmia, and high-degree AV block was managed with an automatic implantable cardioverter-defibrillator (AICD) and a Cordis Multicor II VVI pacemaker. During a routine follow-up visit, the pacemaker threshold was determined. Seven seconds after reprogramming the Cordis pacemaker to the "stat" VVI mode, the AICD discharged. The time to discharge after reprogramming the pacemaker equalled the previously determined AICD charge time. No other rhythm disturbance was documented and the rate with double counting of pacemaker stimulus and QRS complex was less than the triggering rate for the AICD. In conclusion, the AICD can be triggered by pacemaker programming signals unrelated to subsequent pacemaker function.
一名患有特发性扩张型心肌病、药物难治性持续性室性心律失常和高度房室传导阻滞的中年男性,接受了植入式自动心脏除颤器(AICD)和Cordis Multicor II VVI起搏器治疗。在一次常规随访中,测定了起搏器阈值。将Cordis起搏器重新编程为“stat”VVI模式7秒后,AICD放电。重新编程起搏器后至放电的时间与先前测定的AICD充电时间相等。未记录到其他节律紊乱,起搏器刺激和QRS波群双重计数的心率低于AICD的触发率。总之,AICD可由与随后起搏器功能无关的起搏器编程信号触发。
