Non-Invasive Fetal Electrocardiogram Extraction Based on Novel Hybrid Method for Intrapartum ST Segment Analysis

This study focuses on non-invasive fetal electrocardiogram extraction based a novel hybrid method, which combines the advantages of non-adaptive and adaptive approaches for morphological analysis. Besides estimating heart rate, is main parameter used in clinical practice, this provides ST segment analysis data from Abdominal Direct Fetal Electrocardiogram Database consisting simultaneous traditional - gold standard invasive scalp electrode recorded during delivery. innovative approach utilizing combination independent component recursive least squares algorithms has potential to extract valuable information order identify eventual sign distress. was prospective observational electrocardiogram, using 4 abdominally sited electrodes, against 8 patients. In terms rate estimation, accuracy high all tested patients with average value equaled 0.20 beats per minute 1.96 deviation 5.80 minute. 7 patients, it possible perform determining T/QRS comparison reference signal values 0.008 0.031 respectively. thus demonstrates that feasible fECG proposed method.
