May enhance obscured fetal ECG detection in noise; leaves open clinical validation before practice consideration.
The paper discusses signal processing techniques (autocorrelation and crosscorrelation) to detect weak foetal electrocardiograms that are otherwise obscured by baseline noise or muscle disturbance.
Jan H. van Bemmel (1968) studied Pregnancy (Foetal Electrocardiogram). Autocorrelation and crosscorrelation of envelopes was evaluated on Detection of weak foetal electrocardiograms. Autocorrelation and crosscorrelation of envelopes are proposed to detect weak foetal electrocardiograms that are obscured by baseline noise or muscle disturbance.
