Abstract
Current methods of non-invasive fetal heart rate surveillance
Highlights
The evaluation of fetal well-being during labor has been a significant consideration in obstetrics throughout the years
A circadian interdependency between Maternal Heart Rate (MHR) and Fetal Heart Rate (FHR) [2], signal interference from the movement of both the fetus and the mother, further maternal noise from uterine contractions, respiration, abdominal muscle artifacts, as well as electrical noise from the device and power line are just some of the problems that these new devices are called to face [3]
Electronic fetal monitoring (EFM) by means of cardiotocography, electrocardiography, and other methods is an essential tool towards effective fetal assessment during labor [9, 10]
Summary
The evaluation of fetal well-being during labor has been a significant consideration in obstetrics throughout the years. Electronic fetal monitoring (EFM) by means of cardiotocography, electrocardiography, and other methods is an essential tool towards effective fetal assessment during labor [9, 10] This state of the science review focuses on the most recent available scientific data regarding the role of noninvasive electrocardiographic monitoring and its effect on perinatal outcomes. The lack of real-time beat to beat data, frequent repositioning of the transducers causing up to 40% signal loss, the inability to always discriminate between MHR and FHR, and an array of well-documented artefacts have stigmatized this method [1, 13,14,15] It is not implemented even when upgraded with wireless parts, as it restricts mobility much more so than newer technologies [14, 16].
