Electromagnetic inference is a recognized difficulty in concomitant cardiac pacing and nerve stimulation. A case is reported in which a vertebral nerve stimulator was implanted, with a transmitter antenna distal to the right nipple. Six months later, intermittent S-A block with Adams-Stokes attacks urgently necessitated cardiac pacing. The ECG lead II showed nerve stimulator potentials of 0.75 mV. Intracardiac electrogram with unipolar electrode registered potential of 0.25 mV, but with a bipolar system no such potentials were observed. A bipolar pacing electrode was therefore implanted, with an interference from the nerve stiumluator. Various aspects of interference are discussed.
电磁干扰是心脏同步起搏和神经刺激中一个公认的难题。本文报道了一例病例，患者植入了椎旁神经刺激器，其发射天线位于右乳头下方。六个月后，患者出现间歇性窦房阻滞并伴有阿-斯综合征发作，急需进行心脏起搏。心电图II导联显示神经刺激器电位为0.75mV。单极心内电图记录到的电位为0.25mV，但使用双极系统时未观察到此类电位。因此，植入了一个双极起搏电极，受到了神经刺激器的干扰。文中讨论了干扰的各个方面。
