Technical standards for fetal ECG must be met in practice; leaves open impact on perinatal outcomes pending prospective validation.
Accurate fetal ECG analysis requires meticulous technique to minimize signal loss and 1 ms precision for beat-to-beat variability assessment.
G. S. Dawes (1993) conducted a review in Fetal monitoring. Fetal ECG was evaluated. Fetal ECG signal loss can be kept below 5% in routine practice, and beat-to-beat measurement accuracy must be 1 ms to reliably assess short-term variability.
