The study on conduction of fetal ECG by mathematical multi-layer model

One of the most difficult problems is how to find the proper electrode positions on maternal abdomen from which the optimal fetal ECG can be obtained for perinatal monitoring. For this, a study on volume conduction of fetal ECG between source and the maternal abdomen by mathematical multi-layer model was carried out. FECG Potential distribution analysis on fetal vernix caseosa instead of current dipole was presented. A suitable finite clement method was designed for calculation. The result of a clinical case indicated that the potential distribution analysis on fetal vernix caseosa is meaningful.
