Fetal Heart Rate Monitoring prior to and during labor and delivery is a common clinical practice, that guides therapy and decision making. A non-stress test (NST), also known as fetal heart rate (fHR) monitoring, is a common prenatal test used to check on a baby's health. The maternal electrocardiogram (mECG) is generally the most prominent signal present in abdominal NST recordings. Therefore, the mECG needs to be removed to enable reliable and accurate fHR detection. While the NST is non-invasive, current techniques of data acquisition use a limited sampling frequency (as low as 4Hz) which limits the quality of the information available, and prevents the use of mathematical techniques to process the data for better interpretation and to differentiate between the fHR and mECG signals.
