Abstract

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 µT on a railroad platform (electric field: 270 V/m). EMI inside a railroad car (10 µT, 0 V/m) was comparable to the electromagnetic field at the platform. Inside a voltage transformer substation (0 µT, 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. Bioelectromagnetics 28:402–405, 2007. © 2007 Wiley‐Liss, Inc.
