Background Smartphone can emit two types of electromagnetic waves, static field from magnet and dynamic field from calling. Previous evidence showed the interference effects from old generation of mobile phones to cardiac implantable electronic device (CIEDs). The current generation of smartphones and CIEDS are reportedly better designed to reduce electromagnetic interference (EMI). We seek to find the presence and the magnitude of EMI from the current generation of smartphones.

智能手机的电磁干扰对心脏植入式电子设备的影响（EMI-PHONE 研究）

背景智能手机可以发射两种类型的电磁波，磁铁产生的静态场和通话产生的动态场。先前的证据表明，老一代手机对心脏植入式电子设备 (CIED) 的干扰影响。据报道，当前一代的智能手机和 CIEDS 设计得更好，可以减少电磁干扰 (EMI)。我们试图从当前一代智能手机中找出 EMI 的存在和程度。
