Purpose: Automated external defibrillators (AEDs) could not recommend shock for ventricular fibrillation in the presence of electromagnetic interference. The purpose of this study was to examine the effect of an induced electromagnetic field on performance of AED. Methods: The intensity of magnetic waves from commercial electric mats was measured. Three AEDs were attached to the resuscitation manikin and the question of whether shock would be recommended for simulated electrocardiogram of VF or normal sinus rhythm was tested. The simulation was repeated 10 times under the influence of 0, 5, and 18 μT magnetic field or electric mat. Relevant literature studies on electromagnetic interference on AED were reviewed. Results: The magnetic flux density from the electric mat was measured to 5.67-6.1 μT in warming phase, and 2.25-2.84 μT in maintenance phase. There was no false positive or false negative recommendation of shock under the influence of 0, 5, and 18 μT magnetic field or electric mat. However, one AED detected motion even in the stationary state. Among 11 studies from the literature search, five studies reported misinterpretation of AED. Minor errors including delayed analysis, motion artefact, and noise in speakers were reported from 6 studies. Conclusion: Although we could not reproduce false negative interpretation, AED made a mistake in confusing electromagnetic interference with motion artefact. Therefore, emergency providers should be cautious not to use AED close to household appliances or medical equipment inducing electromagnetic interference.
