Key result
Fetal acidosis was associated with prolonged QT and T-wave inversion, but scalp blood pH provided a more reliable method than corrected QT times for predicting fetal condition at birth.
Why the study?
Does fetal electrocardiogram configuration correlate with fetal acid-base balance and plasma electrolytes in at-risk fetuses?
Population
102 cases in which the fetus was considered to be 'at risk'

Scalp pH remains preferable to QT for intrapartum prediction; cohort data leave ECG's added value open.

Does fetal electrocardiogram configuration correlate with fetal acid-base balance and plasma electrolytes in at-risk fetuses?
While fetal acidosis and hyperkalemia correlate with QT prolongation and T-wave inversion on fetal ECG, scalp blood pH remains a more reliable predictor of fetal condition at birth.
E. M. Symonds (1971) conducted an observational in At-risk fetus (n=102). Fetal acidosis and plasma electrolytes was evaluated on Prediction of fetal condition at birth. Fetal acidosis was associated with prolonged QT and T-wave inversion, but scalp blood pH provided a more reliable method than corrected QT times for predicting fetal condition at birth.
