WebThe antenatal cardiotocography (CTG) in Figure 1 was recorded from a primigravid woman at 41+4 weeks gestation. She was being monitored for post-dates. The AFI was reported at 12cm. With a baseline fetal heart rate of 90–95bpm, normal baseline variability and accelerations, this is a well-oxygenated fetus. WebStudies on inter- and intra-observer variability have shown that the introduction of computer-assisted classifications of CTG readings has resulted in a more reliable categorization of CTG patterns overall 37, 46. The benefit of “online” CTG analysis is that asssessment can be done almost in realtime.
