摘要: The purpose of this study is to highlight the dynamic relationship between cardiotocographic signals: intrapartum fetal heart rate and uterine pressure, for normal hypoxic fetuses. database used in our contains 531 or abnormal recordings (abnormal are considered those with pH value under 7.15). We have partial directed coherence (PDC) method obtain correlation parameter values investigate coupling contractions recordings. To determine difference levels we divide into two groups: 100 as a control group, remaining 431 test order apply t-test p<0.05 parameters obtained. computed standard deviation Shannon entropy obtained PDC complexity correlation.
