T-Wave Alternans Identification in Direct and Indirect Fetal Electrocardiography

The fetal electrocardiogram (FECG) is the recording of the electrical activity of the fetal heart. Morphologically, FECG shows the standard P-QRS-TU electrocardiographic pattern and a heart rate (HR) of 120–160 bpm. There are two techniques to acquire FEC

Preface

Pregnancy is a critical time for the health of mother and fetus, with significant risks for both. Early prenatal diagnosis can enable therapeutic interventions in utero or postpartum (or childbirth programming through cesarean section) in order to minimize risks for the fetus in the short and long term. Tools for pregnancy monitoring can as well be adopted to follow the mother and baby throughout gestation, up to labor and more, in case something goes wrong. In particular, the perinatal period, spanning from the third trimester of pregnancy up to 1 month after birth, is most critical for the baby. For this reason, in the last decades, biomedical engineering supported and fostered scientific research towards identification of new models, parameters, algorithms, and tools that can improv
