Full decoding of CTG during pregnancy

CTG helps the doctor during one study to study two important parameters of pregnancy and fetal development at once. First, the child's heart rate is studied, and secondly, the tone of the uterus.

The expectant mother can find out if there are any abnormalities in the development of the fetus or the course of pregnancy. In addition, CTG will promptly eliminate and correct problems if they arise in the early stages of pregnancy.

Decoding CTG during pregnancy

During the procedure, the doctor receives and analyzes several parameters at once.

1. Average fetal heart rate

The so-called basal rhythm should normally be in the range of 110-160 beats per minute.

2. Heart rate variability

The average deviation from the optimal heart rate parameters can be from 10 to 25 beats per minute in either direction.

3. Acceleration 

It is fixed if the heart rate accelerates by 15 beats per minute for 15 or more seconds. The graph is represented by teeth. Normally, acceleration should occur in a child no more than 2 times during a ten-minute monitoring.

4. Deceleration

The parameter, which is the opposite for the previous one, and is associated with a decrease in the basal rhythm by 15 or more beats from 15 seconds.

normal circumstances is not recorded, because it speaks of fetal hypoxia.

CTG result in points

CTG is evaluated in a point system, so the expectant mother will see a certain number of points in the doctor's conclusions.

• From 0 to 4 points - there are violations, it is necessary to carry out a diagnosis.
• From 5 to 7 points - disturbances in the functioning of the fetal cardiovascular system are likely, it is recommended to repeat CTG.
• From 8 to 10 points - the baby's heart is working perfectly!
