An 82-year-old man with a permanent pacemaker (PM) implanted for sick sinus syndrome complained of palpitation due to paroxysmal atrial fibrillation and flutter. During extensive pulmonary vein isolation, the atrial lead was dislodged to the level of the tricuspid annulus. Radiofrequency energy delivery to the cavotricuspid isthmus reproducibly caused twitching of the PM pocket. The atrial lead was repositioned to the right atrial appendage, PM check revealed no functional change in the PM or lead performance. This is the first reported case of twitching of the PM pocket due to electromagnetic interference.
一名82岁因病态窦房结综合征植入永久起搏器(PM)的男性,因阵发性心房颤动和扑动而主诉心悸。在广泛的肺静脉隔离过程中,心房导线移位至三尖瓣环水平。向腔静脉-三尖瓣峡部输送射频能量可重复性地导致起搏器囊袋抽搐。心房导线重新定位至右心耳,起搏器检查显示起搏器或导线功能无变化。这是首例因电磁干扰导致起搏器囊袋抽搐的报道病例。
