Linear models of intrapartum uterine pressure-fetal heart rate interaction for the normal and hypoxic fetus.
We construct input-output models by linear system-identification methods for uterine pressure - fetal heart rate data collected during labour and delivery. Using standard hypothesis tests, the impulse response model coefficients show statistically significant differences between normal and pathological cases.
