Maternal DM associated with increased fetal ST depression; leaves open whether FECG criteria require adjustment in this population.
Does maternal diabetes mellitus increase the prevalence of ST-segment changes on fetal ECG during labour in term fetuses?
Fetuses of mothers with diabetes have a significantly higher prevalence of intrapartum ST depression on ECG, which may reflect an altered myocardial response to labour stress rather than hypoxia.
