电磁炉和ICD。电磁场可能会干扰正常的植入式心律转复除颤器（ICD）功能。尽管这些器械被有效屏蔽，并且仅使用双极导线，但当患者接触多种家用电器时，电磁干扰（EMI）仍然是一个问题。这项研究的目的是评估潜在的电磁干扰风险的感应炉，这是越来越普遍的私人家庭。用于私人家庭的感应炉GK 43 TI（V-Zug，Inc.，Zug，Switzerland）表明，通过将操作时间从1级（100 ms/sec）增加到5级（连续操作）来调节加热。从5级到9级，磁场会增加。本研究纳入了19例左侧植入单腔和双腔ICD系统的患者（Medtronic 8例，Guidant 7例，St. Jude Medical 4例）（18例男性，1例女性），年龄（平均值+/- SEM）58 +/- 3岁。所有患者均以站立位进行检查，弯腰放在烹饪锅上（与感应线圈的最小距离为25 cm），并将烹饪锅偏心放置在三个不同烹饪水平（水平2，5和9）的感应场上。用一只手触摸烹饪锅重复测试。心室敏感性保持不变。Medtronic和Guidant器械中的室性心动过速治疗被关闭，在测试期间，St. Jude Medical器械中的心室感知被持续监测。暴露后对器械的询问未显示任何不适当的心动过速检测、过感知或重新程控。总之，ICD患者可以放心，如果在厨房使用感应炉，EMI不太可能影响他们的设备。
Induction Ovens and ICDs.Electromagnetic fields may interfere with normal implantable cardioverter defibrillator (ICD) function. Although the devices are effectively shielded and use exclusively bipolar leads, electromagnetic interference (EMI) remains a concern when patients are exposed to several household appliances. The aim of this study was to evaluate potential EMI risk of induction ovens, which are increasingly common in private households. In vitro measurements of an induction oven for private households GK 43 TI (V-Zug, Inc., Zug, Switzerland) showed that heating is regulated by increasing operating time from level 1 (100 ms/sec) to 5 (continuous operation). From levels 5 to 9 the magnetic field increases. Nineteen patients with left-sided implants of single- and dual-chamber ICD systems (8 Medtronic, 7 Guidant, and 4 St. Jude Medical) (18 males, 1 female), age (mean +/- SEM) 58 +/- 3 years, were included in this study. All patients were examined in standing position, bent over the cooking pot (minimal distance to the induction coil 25 cm), and with the cooking pot put eccentrically over the induction field at three different cooking levels (level 2, 5, and 9). The tests were repeated touching the cooking pot with one hand. Ventricular sensitivity was left unchanged. Ventricular tachycardia therapies were turned off in Medtronic and Guidant devices and ventricular sensing was continuously monitored in St. Jude Medical devices during testing. Interrogation of the devices after exposure did not show any inappropriate tachycardia detection, oversensing, or reprogramming. In conclusion, ICD patients can be reassured that EMI is unlikely to affect their devices if induction ovens are used in their kitchens.
