Key result
An antepartum short-term fetal heart rate variation ≤3.0 ms was associated with a higher rate of metabolic acidaemia compared to >3.0 ms (54.2% vs 10.5%; P<0.001) in growth-retarded fetuses.

Does short-term fetal heart rate variation predict perinatal outcome in severely growth-retarded fetuses?
Absolute Event Rate: 54.2% vs 10.5%

Antepartum short-term fetal heart rate variation is an important marker for predicting metabolic acidemia and perinatal outcomes in severely growth-retarded fetuses.
Serra et al. (2008) conducted a cohort in Severely growth-retarded fetuses (n=257). Short-term fetal heart rate variation (STV) ≤ 3.0 milliseconds vs. STV > 3.0 milliseconds was evaluated on Metabolic acidaemia (p=<0.001). An antepartum short-term fetal heart rate variation ≤3.0 ms was associated with a higher rate of metabolic acidaemia compared to >3.0 ms (54.2% vs 10.5%; P<0.001) in growth-retarded fetuses.
