摘要/Abstract

摘要： 为研究电磁场对生物体心电信号复杂度的影响，在20mT，50Hz交变电磁场环境中曝露大鼠，连续曝露7d，采集大鼠磁场曝露前、磁场曝露10，20和30min心电信号(ECG)，利用经验模态分解(EMD)重构信号，计算各信号多尺度熵(MSEn).实验结果表明，20mT，50Hz交变磁场对大鼠心电信号多尺度熵的影响具有时间效应，通过心脏的自我调控可以降低交变磁场对大鼠心脏的影响.

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
