A new automated method for estimation of the gestational age is presented in this paper based on the intervals between fetal cardiac valve timings and the Q-wave of fetal electrocardiogram (fECG). The intervals were estimated automatically from one-dimensional Doppler Ultrasound and noninvasive fECG. Among the intervals, Isovolumic Contraction Time, Electromechanical Delay Time, Ventricular Filling Time and their interactions were selected in a stepwise regression process. Compared with

Since valve intervals reflect the autonomic function, this method provides a novel measure of the development of fetal autonomic nervous system that may be growth curve independent. One-dimensional Doppler Ultrasound (1-D DUS) data were obtained using ultrasonic transducer 5700 (Coromet-
