Although automated external defibrillators (AEDs) are available for public responders in metro stations, electromagnetic interference (EMI) of metro stations and cellular telephones may weaken the signal quality of an AED. We assessed the influence of metro stations EMI, with or without the interference of digital cellular telephones, on the performance of AED. We observed the most significant interference on the rhythm analysis with the combination of the incoming train and cellular telephone operation.
