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. WebInter- and intraobserver agreement in CTG interpretation using the FIGO score and the computer analyzing software was assessed via proportions of agreement (Pa), with 95% confidence intervals. The level of inter- and intraobserver agreement was analyzed by calculating Pa values for CTG baseline, variability, accelerations and decelerations.
