7/12/18 femu systematic review on EMI in cardiac implants caused by intermediate frequency fields

The Journal EP Europace has published a systematic review performed by femu with the title: „Electromagnetic interference in cardiac electronic implants caused by novel electrical appliances emitting electromagnetic fields in the intermediate frequency range: a systematic review“. The aim of this systematic review was to evaluate whether cardiovascular implantable electronic devices (CIEDs) are susceptible to electromagnetic interference (EMI) in the IF range (1 kHz–1 MHz). The analysis showed that cardiac implants are susceptible to EMI in the intermediate frequency range, particularly through security systems and induction hobs. The likelihood for EMI is dependent on different exposure-related parameters (field strength, frequency and modulation) and on the implanted devices and leads (model, type of implant, implant sensitivity setting, lead configuration and implantation site). However, the factors influencing EMI have not yet been sufficiently characterized to derive exposure limit values. Future studies should therefore consider exposure-related parameters as well as implant- and lead-related parameters systematically. Additionally, worst-case scenarios should be considered in all study types where possible.

The study was supported by the European Research Group on Environment and Health in the Transport Sector (EUGT) e.V., Germany.
