Why the study?
Does intrapartum hypoxia affect the fetal QT and QTc intervals during labour?
Population
136 fetuses (68 acidemic at birth with pH <7.05 and BD >12 mmol/L, and a control group of similar size)…
Comparison
Intrapartum hypoxia (acidemic at birth) vs Control group (non-acidemic at birth)
Design
Cohort
Follow-up
Intrapartum period (until birth)

QTc shortening may mark intrapartum acidosis; hypothesis-generating for fetal QTc monitoring, needs prospective validation.
Does intrapartum hypoxia affect the fetal QT and QTc intervals during labour?
Intrapartum hypoxia resulting in metabolic acidosis is associated with a significant shortening of the fetal QT and QTc intervals, suggesting these parameters may provide additional information for fetal monitoring.
