There are increasing numbers of radiofrequency current ablation procedures being reported. Selected patients have antitachycardia or antibradycardia pacemakers. The pacemaker behavior during and after ablation procedures differs widely. We report on the pacemaker reaction of 25 patients with 13 different devices, most with unipolar electrodes. Sensing failures were observed in 8 (32.0%) and pacing failures in 4 (16.0%) patients. Prolonged pauses and induction of tachyarrhythmias were observed. No pacemaker damage was seen although it is reported by other investigators. We recommend deactivation of implanted generators and an external bipolar pacing electrode. Manufacturers should focus their attention on this problem and protect the generators and their functions for 500 kHz radiofrequency current.
据报道,进行射频电流消融手术的病例数量在不断增加。部分患者植入了抗心动过速或抗心动过缓起搏器。消融手术期间及术后起搏器的行为差异很大。我们报告了25例使用13种不同设备的患者的起搏器反应情况,大多数设备带有单极电极。8例(32.0%)患者出现感知故障,4例(16.0%)患者出现起搏故障。观察到有长时间停顿和快速性心律失常的诱发情况。尽管其他研究者有相关报告,但我们未观察到起搏器损坏。我们建议停用植入式发生器并使用外部双极起搏电极。制造商应关注这一问题,并针对500千赫兹射频电流保护发生器及其功能。
