From 1971 to 1974 in the Department of Gynecology and Obstetrics of the Humboldt-University of Berlin we monitored 1132 fetuses. The extent of the analysed groups runs to 306 to 632 cases, according to the completeness of the investigations and documentation. We have compared our CTG-findings with those of other authors. We found relationships between the risk factors and the CTG findings: for low weight fetuses more frequent Dip I, for maternal vitium cordis more frequent fetal tachycardia, for meconium stained liquor more frequent smooth baseline (silent) for EPH-gestosis (toxemia) more frequent Dip II (late deceleration) and variable deceleration. The relationships between the risk factors and the CTG findings are loose and not suitable to verify the great differences in frequency of the CTG pattern, published in the literature. We believe, that these differences are caused by different definitions and subjective interpretation of the CTG.
