We describe 2 cases of electromagnetic interference (EMI) with a transcutaneous electrical nerve stimulation (TENS) device in patients with implantable cardioverter-defibrillators (ICDs). Both patients were using DR-HO'S pain therapy system for chronic back pain (VGH Solutions Inc., Markham, ON, Canada). In both cases, EMI was inappropriately labeled as ventricular fibrillation. In the first case, the noise detected was of a short duration and did not fulfill the discriminator criteria to deliver ICD therapy. In the second case, inappropriate anti-tachycardia pacing and shocks resulting from EMI were delivered. Both patients were advised not to use TENS devices at home. Increased awareness of EMI resulting in inappropriate ICD therapies using these devices is needed.
我们描述了2例植入式心脏复律除颤器（ICD）患者使用经皮电神经刺激（TENS）设备时发生电磁干扰（EMI）的病例。两名患者均使用DR-HO'S疼痛治疗系统治疗慢性背痛（加拿大安大略省万锦市VGH Solutions公司）。在这两例病例中，EMI均被误标记为室颤。在第一例病例中，检测到的噪声持续时间较短，未达到启动ICD治疗的鉴别标准。在第二例病例中，EMI导致了不适当的抗心动过速起搏和电击。建议两名患者在家中不要使用TENS设备。需要提高对使用这些设备导致ICD治疗不当的EMI的认识。
