During gestation the abdominally recorded fetal ECG (FECG) changes as a result of changes in the conductive medium. In particular, a minimum occurs in the FECG amplitude around 30 weeks of gestation. Based on the results of an extensive FECG study, the effect of these changes on the fetal MCG are simulated. It is shown that the FMCG amplitude is not greatly affected by the changes in the conductive medium. The FMCG waveform, however, is.
在妊娠期,由于传导介质的变化,经腹部记录的胎儿心电图(FECG)会发生改变。具体而言,在妊娠约30周时FECG振幅出现最小值。基于一项广泛的FECG研究结果,模拟了这些变化对胎儿磁心电图(MCG)的影响。结果表明,传导介质的变化对胎儿MCG振幅影响不大。然而,对胎儿MCG波形有影响。
