CWT based Fetal ECG signal analysis in terms of R-peaks detection

This paper presents a novel approach for fetal Electrocardiogram (FECG) signal analysis, focusing on accurate R-peak detection using the Continuous Wavelet Transform (CWT). The proposed method leverages the multi-resolution capabilities of CWT to process abdominal ECG signals, enabling precise time-frequency localization for isolating fetal R-peaks. Wavelet thresholding enhances signal clarity and reduces noise, ensuring robust performance in noisy conditions. The approach demonstrates consistent accuracy and F1-score of above 90%, showcasing its effectiveness in non-invasive prenatal monitoring. Despite its computational demands, the method significantly improves the reliability of fetal cardiac analysis, offering a valuable tool for diagnosing and monitoring fetal health.
