Cahill LS, Stortz G, Chandran AR, et al. - In this prospective longitudinal study, conducted at two study sites, researchers sought to assess the feasibility of using umbilical artery (UA) Doppler waveforms to measure fetal heart rate (FHR) short‐term variation (STV) across gestation. One hundred ninety-five women who underwent ultrasound examinations throughout gestation were involved in the study population. Findings suggested that UA Doppler waveforms provide a robust and viable method to derive STV of the FHR. It should be stressed that the UA Doppler-derived STV is not interchangeable with computerized cardiotocography measurements. In order to determine the importance of concurrent fetal cardiovascular and heart rate evaluations that are possible with the technique mentioned here, further investigations are therefore required to confirm associations with outcome.
