Key result
Fetal QRS duration measured via maternal abdominal ECGs showed a highly significant relation with birth weight, allowing prediction of birth weight with a standard deviation of 302 g.

Does fetal QRS duration measured via abdominal ECG correlate with fetal maturity and birth weight in uncomplicated pregnancies?
Fetal QRS duration measured via abdominal ECG correlates closely with fetal maturity and can predict birth weight with reasonable accuracy.
Brambati et al. (1980) conducted a cross-sectional in Uncomplicated pregnancies (n=421). Fetal electrocardiogram (ECG) QRS duration measurement was evaluated on Relation between QRS duration and fetal maturity/birth weight. Fetal QRS duration measured via maternal abdominal ECGs showed a highly significant relation with birth weight, allowing prediction of birth weight with a standard deviation of 302 g.
