Public concern for the compatibility of electromagnetic (EM) sources with active implantable medical devices (AIMD) has prompted the development of new systems that can perform accurate exposure studies. EM field interference with active cardiac implants (e.g. implantable cardioverter-defibrillators (ICDs)) can be critical. This paper describes a magnetic field (MF) exposure system and the method developed for testing the immunity of ICD to continuous-wave MFs. The MFs were created by Helmholtz coils, housed in a Faraday cage. The coils were able to produce highly uniform MFs up to 4000 µT at 50 Hz and 3900 µT at 60 Hz, within the test space. Four ICDs were tested. No dysfunctions were found in the generated MFs. These results confirm that the tested ICDs were immune to low frequency MFs.
公众对电磁（EM）源与有源植入式医疗器械（AIMD）兼容性的关注促使开发了能够进行精确暴露研究的新系统。EM 场对有源心脏植入物（例如植入式心脏复律除颤器（ICD））的干扰可能是关键的。本文描述了一种磁场（MF）暴露系统和开发的用于测试 ICD 对连续波 MF 免疫力的方法。MF 由亥姆霍兹线圈产生，放置在法拉第笼中。这些线圈能够在测试空间内产生高达 50 Hz 时 4000 µT 和 60 Hz 时 3900 µT 的高度均匀 MF。对四个 ICD 进行了测试。在产生的 MF 中未发现功能障碍。这些结果证实，所测试的 ICD 对低频 MF 具有免疫力。
