Research Abstract

A method for detecting a peak corresponding to an electrocardiographic R wave from Doppler heart rate signals was devised to clarify autonomic functions of fetuses during pregnancy and the intrapartum period. In order to verify the validity of this detection method, evaluation of heart rate signals and electrocardiography was conducted simultaneously in adults and newborns and the correlation of these data was examined. The results indicated that these data had a high correlation and could be used for the study. Measurements were conducted on pregnant women to examine the autonomic functions of fetuses and the synchronism between mothers and fetuses. In order to develop this study in the future, the adequateness of the peaks detected in fetuses will be verified by using echographic images, etc.
