Opportunities of the estimation of the state of the fetus ising the method of the fetal cardiac signal extraction and analysis

Abstract


The character of the cardioelectric potential distribution is the diagnostic indication of the cardiovascular system state. Signals recorded from maternal abdomen besides the useful component - the fetal electrocardiogram - also contain artefacts; the maternal electrocardiogram, mother's muscles activity or artifacts resulting from fetal movements. Essential problem is the efficient suppression of maternal electrocardiogram, since its amplitude many times exceeds the level of the useful signal and the frequency bands of maternal and fetal electrocardiographic signals overlapped. A computational scheme is represented for the fetal electrocardiographic mapping. This experience will allow us to come up with a system for effective diagnostics of early symptoms of fetal distress on the basis of recording and analysis of the bioelectrical signals recorded only from the abdomen.
