| Summary: | An algorithm has been developed for the
simultaneous measurement of the fetal and maternal heart
rates from the maternal abdominal electrocardiogram during
pregnancy and labor. The algorithm is based on digital
filtering, adaptive thresholding, statistical properties in the
time domain and differencing of local maxima and minima.
The technique has been developed through a combination and
modification of earlier techniques making it suitable for
ambulatory monitoring. Eighteen volunteers at various weeks
of gestation were studied for the fetal heart rate detection.
The computation complexity is such that the developed
algorithm can extract both maternal and fetal heart rates in
real-time utilizing a single-lead configuration. |
