May support PEP/VET ratio for asphyxia prediction in suspected distress; hypothesis-generating and requires prospective validation before practice change.
Does combined analysis of fetal ECG and systolic time intervals during labor predict fetal asphyxia in pregnancies with suspected fetal distress?
Combined analysis of fetal ECG and systolic time intervals during labor, particularly the PEP to VET ratio, improves the prediction of fetal asphyxia compared to standard heart rate monitoring.
Lewinsky et al. (1992) studied this question.
