Cardiotocography (CTG) is a diagnostic method of fetal monitoring, ie. its vulnerability during pregnancy and childbirth using special devices.
Cardiotocography CVS or part KTG (CTG) includes a graphical display of fetal heart activity and the activity of the muscles of the wall of the uterus during pregnancy and during the birth. The method consists of the simultaneous contraction of the uterus and the fetal heart rate. Contraction of uterus (contraction) and fetal heart rate is recorded by means of special probes that are placed on the anterior abdominal wall (skin on the abdomen). In the device different pulses are converted into signals displayed on a monitor and recorded on a separate movable bar paper. On the basis of the lines appearances (curve), the condition of the fetus is determined, and its possible threat during pregnancy or during birth.
Cardiotocography (CTG) can be applied from 28 week of pregnancy, but its most common use after the 32nd week. It is especially important cardiotocographic monitoring of high-risk pregnancy, when pregnant women with diabetes have high blood pressure, if they are Rh-negative, when they have long been treated for infertility, if they are so called, elderly primiparae, during transferred pregnancy.
We advise CTG every two weeks, if necessary (to assess the risk pregnancies), and every seven days.
