Abstract: In order to research the effect of electromagnetic field on the complexity of ECG in organisms, the rats were exposed to 20mT, 50Hz alternating electromagnetic field environment for seven consecutive days. The ECGs of rats which were exposed to the magnetic field for 0, 10, 20 and 30minutes, were collected. The signals were reconstructed using empirical mode decomposition(EMD), and then the multiscale entropy(MSEn)of each signal was calculated. The results showed that the 20mT, 50Hz alternating magnetic field has a time effect on the multi-scale entropy of rat’s ECG, based on which the effect on the rats can be reduced by cardiac self-regulation.

Key words: ECG of rats, magnetic expose, EMD, MSEn, alternating electromagnetic field
