A new procedure is presented to extract fetal electrocardiograms from maternal abdominal recordings. It consists of a series of smart digital filters, tremplate matching and template subtraction, that allow obtaining a tracing with the only clean FECG.With the method described, the R-R intervals for mother and fetus are calculated and plotted.
