Fetal ECG Preprocessing Using Wavelet Transform

Abstract

Fetal electrocardiography is one of the most promising methods of Electronic fetal monitoring, which helps physicians to assess the fetal well-being diagnose the hypoxic states. This paper focuses on introducing Wavelet Transform as an effective tool to suppress the most frequent types of fetal electrocardiogram interferences, such as powerline or myopotential interference. We also suggest optimal type of the wavelet and threshold for this purpose.
