Monitoring Fetal Heart Rate during Pregnancy: Contributions from Advanced Signal Processing and Wearable Technology

<table>Example of CTG graph. The upper trace is fetal heart rate signal obtained by a Doppler ultrasound probe; the baseline is drawn and the arrows represent the detected accelerations. The lower tracing is the toco signal (uterine contractions). Time units are in minutes.</table>
