Non‐invasive fetal electrocardiography in singleton and multiple pregnancies

Abstract: Objectives To document the duration of fetal cardiac time intervals in uncomplicated singleton pregnancies using a novel non-invasive fetal electrocardiography (fECG) system and to demonstrate this technique's ability to acquire recordings in twin and triplet pregnancies. Design Prospective cross sectional observational study.Setting Antenatal wards and clinics, day assessment unit and centre for fetal care at a tertiary referral hospital, London, UK. Population or Sample Three hundred and four singleton and m… Show more

“…A full fECG signature (including T waves) was obtained in 31 of the 35 (88.6%) separated signals. We have previously published reference ranges for fECG time intervals in a singleton cohort of 199 normal fetuses 15. A prolonged PR interval was defined as one lying above 95% gestational age-related confidence intervals (95% CI).…”

“…All mPR and ePR intervals measured in this study were plotted against published reference ranges (fig 1). 13 15 In most cases the mPR was longer than ePR because it includes electromechanical delay and isovolumic contraction time.…”

“…The twin pregnancy problem was relatively rarely discussed, except in Niknazar et al [17] and Taylor et al [65]. In Case 5 of the simulated database, although we do not specifically study in this paper, we mention that the proposed algorithm has the potential to handle even multiple pregnancy problem.…”
