WebJan 5, 2010 · The cardiotocogram (CTG) recorded during the labor. Fetal heart rate (FHR) is traced in the upper channel and uterine contraction in the lower one. The CTG is normal and reassuring because of normal baseline level, normal baseline variability, transient FHR accelerations but no transient deceleration. The time bar represents 1 minute.
WebBaseline heart rate – average baseline fetal heart rate. Reassuring feature: 110 – 160 beat per minute (bpm) Non-reassuring feature: 100 – 109 bpm OR 161 – 180 bpm; Abnormal feature: < 100 bpm OR > 180 bpm; Variability – Fluctuations in the fetal heart rate This causes the tracing to appear as a jagged, rather than a smooth, line.
