这项工作的目标是实施一套专门用于表征心脏起搏器在低频电磁干扰下的免疫力的计量装置。研究频率分别为50赫兹、60赫兹、10千赫和25千赫。所采用的评估方法与电磁兼容是一致的。测试是在单腔起搏器上进行的。第一种方法包括在起搏器外壳和电极之间直接施加干扰信号，使我们能够指出预设的检测灵敏度对终端和起搏器外壳之间感应的信号电平的影响。这些尝试是通过使用电磁模型的体外测试完成的，该模型允许人们考虑构成人体的界面，从而更接近真实的生活情况。起搏器产生的信号的可视化说明了起搏器根据不同测试配置的性能。这是一种初步的方法，旨在为制定计量协议奠定基础。
The goal of this work is the implementation of a metrological set up dedicated to the characterization of cardiac pacemakers' immunity at low frequency electromagnetic disruptions. The studied frequencies are 50 Hz, 60 Hz, 10 kHz and 25 kHz. The assessment methodology that is applied is in accord with the electromagnetic compatibility. The tests are carried out on single-chamber pacemakers. The first approach, consisting of the application of the interfering signal directly between the housing and the electrode, enabled us to point out the influence of a preset detection sensitivity on the signal levels induced between the terminal and the pacemaker's housing. These attempts are completed by in vitro tests using an electromagnetic model which allows one to take into account the interface which constitutes the human body, and thus to get closer to a real life situation. The visualization of the pacemaker generated signal illustrates the performance of the pacemaker according to different test configurations. It is an initial approach meant to create a base for the creation of a metrological protocol.
