Cardiotocogram (CTG) is the most widely means for the assessment of fetal condition. CTG consists of two traces one depicting the Fetal Heart Rate (FHR), and the other the Uterine Contractions (UC) activity. Many automatic methods have been proposed for the interpretation of the CTG. Most of them rely either on a binary classification approach or on a multiclass approach to come up with a decision about the class that the tracing belongs to. This work investigates the use of a one-class approach to the assessment of cardiotocograms building a model for the healthy data. The preliminary results are promising indicating that normal traces could be used as part of an automatic system.
