Abstract

Fetal ECG monitoring is essential for identification of fetal distress. The assessment of the QRS waveform of fetal ECG is good analysis tool. Extraction of fetal ECG from abdominal signals is difficult. This paper presents a method for extracting fetal ECG (FECG) from composite abdominal signal. This method is applied to composite abdominal signal containing maternal ECG and fetal ECG. Adaptive filtering techniques along with denoising techniques were used to extract fECG. This method leads to enhancement of fetal ECG by cancelling maternal ECG. The results were validated using real signals. The thoracic signal is purely that of mother (mECG) while the abdominal signal contains both mothers and fetus ECG signals (mECG + fECG). The results clearly show the effectiveness of the method in extracting fECG.
