Comprehensive method for extraction of fetal electrocardiosignals from maternal abdominal signals
Main Article Content
Abstract
The article describes a non-invasive method for evaluation of fetal condition using high resolution electrocardiography systems. A comprehensive method for fetal electrocardiosignals extraction from the abdominal maternal signals, which is based on the combined use of principal component analysis, independent component analysis and wavelet analysis, is proposed. The numerical experiments showed that application of the proposed method allowed us to eliminate noise in the abdominal electrocardiogram, as well as to identify pathological changes in the morphology of fetal cardiocycles.
