The journal Expert Review of Medical Devices has published an article by femu entitled: “Interference of Cardiovascular Implantable Electronic Devices by Static Electric and Magnetic Fields”. The aim of this study was to determine thresholds for electromagnetic interference (EMI) of cardiac implants by static electric and magnetic fields. A literature search revealed four interference mechanisms caused by static magnetic fields and none for static electric fields. Due to the scarce information on motion-induced EMI by static magnetic fields, numerical simulations were performed to obtain a threshold. The results showed that motion-induced EMI should not occur below the activation of the magnetic safety switch (MSS) at 0.8 mT. The authors concluded that MSS activation is the most relevant mechanism for static magnetic fields.
