The fetal ECG (fECG) provides a mean to monitor non-invasively the fetal heart activity. Until today, its low signal to noise ratio hampered an extended use of the fECG in clinical practice. As proposed pro- cessing methods have shown a lack of accuracy in certain circumstances, the characterization and fur- ther development of methods to process the fECG is of high interest. This contribution aims at a compar- ative evaluation of two methods, namely a Kalman Filter based approach and a classical template sub- traction approach, regarding their ability to be used in the context of fetal QRS detection. Although both methods prove to be applicable to detect fetal QRS complexes, the Kalman based approach has shown to performmore accurately using simulated and real datasets.
