Exposure to 16.7-Hz electromagnetic fields, such as those near railroads, causes significant interference on surface ECGs, rendering rhythm diagnosis impossible.
The extent of electromagnetic interference (EMI) from 16.7-Hz alternate current power lines in the human surface electrocardiogram (ECG) was evaluated. Results showed a direct linear correlation between mean EMI and magnetic induction of 5.8-21 microT on a railroad platform (electric field: 270 V/m). EMI inside a railroad car (10 microT, 0 V/m) was comparable to the electromagnetic field at the platform. Inside a voltage transformer substation (0 microT, 2000 V/m) EMI occurred only when the ECG device was closer to the power line than the test person. Magnetic induction caused 16.7-Hz EMI to a degree that proper diagnosis of ECG-rhythms was rendered impossible.
