Clinical overview of cardiotocography
BJOG: An International Journal of Obstetrics & Gynaecology, 1993ABSTRACTTwenty years after its widespread introduction, the role of continuous fetal heart rate and contraction monitoring in labour (cardiotocography, CTG) remains uncertain. Although a normal pattern is very reassuring about fetal condition, the predictive value of an abnormal pattern is low. In most studies the use of CTG has been associated with an

Digitization and Analysis of Cardiotocography Records [PDF]
2020 IEEE-HYDCON, 2020 Cardiotocography (CTG) is an essential tool to get access to fetal heart rate which indicates the fetal health. Most of the fetal distress symptoms occur prior to the labor. Abnormal changes in the intensity of uterine contractions during labor cause inconvenience to the fetus and result in fetal heart rate variability, abnormal amniotic fluid levels ...

Classification model for cardiotocographies
2016 11th Iberian Conference on Information Systems and Technologies (CISTI), 2016Cardiotocography is a diagnostic exam performed from the 28th week of pregnancy that registers the fetus cardiac frequency and uterine contractions. From this exam results a cardiotocogram whose reading and observation of the patterns contained in it allow an evaluation of the baby's condition and the fetal vitality in the maternal womb. This work aims

Antenatal Nonstress Cardiotocography
Australian and New Zealand Journal of Obstetrics and Gynaecology, 1987EDITORIAL COMMENT: There are problems with the interpretation of the value of antenatal cardiotocography in current obstetric practice. For example, a recent review by Thacker and Berkelman concluded that although nonstress and contraction stress cardiotocographs are used extensively in the United States of America, ‘neither have been demonstrated to ...

Antenatal Cardiotocography and Intrauterine Death
Acta Obstetricia et Gynecologica Scandinavica, 1980The purpose of the present study was to elucidate The reliability of antenatal cardiotocography (CTG) in predicting fetal death. During a 4‐year period, 1 455 patients with risk pregnancies have been routinely monitored with antenatal CTG. The total number of tracings amounted to inore than 10 000.

Intrapartum cardiotocography and pattern recognition
BMJ, 2018Mullins and Lees debate Brocklehurst about the use of continuous fetal heart rate monitoring.1 The INFANT trial did not test cardiotocography versus intermittent or no auscultation, but rather whether decision support software could aid interpretation of cardiotocographs. The counterargument offered for the major flaw of “learning in the control group”

Quality of intrapartum cardiotocography in twin deliveries
American Journal of Obstetrics and Gynecology, 2004Intrapartum fetal heart rate (FHR) recordings in twins were compared for fetal signal loss during both stages of labor to assess the quality of these recordings by the method that had been used: external ultrasound or directly via a scalp electrode.Analysis of recordings collected between January 1, 1994, and January 1, 2002, from consecutive twin ...

Admission cardiotocography: a randomised controlled trial
The Lancet, 2003Admission cardiotocography is widely used to identify pregnancies that might benefit from continuous electronic fetal monitoring in labour. We aimed to compare the effect on neonatal outcome of admission cardiotocography versus intermittent auscultation of the fetal heart rate.8580 women admitted to the delivery ward of a Dublin teaching hospital who ...

This paper reports on a comparative test of eight cardiotocographic units which compute fetal heart rate on the basis of an ultrasonic signal. In order to ensure comparable test conditions for each unit, consisting of the monitor and the signal recorder, a simple measuring system was built.

STRESSED CARDIOTOCOGRAPHY IN LATE PREGNANCY
BJOG: An International Journal of Obstetrics & Gynaecology, 1971SummaryA method of examination of the fetus in late pregnancy by serial and stressed cardiotocograms is described. The clinical application of this form of investigation is appraised. Advantages and disadvantages of the test are discussed.
