What shows the CTG of the fetus at 32 weeks. CTG during pregnancy what is it and why

To assess the condition of the fetus, doctors prescribe various tests for pregnant women. The most common is ultrasound. In addition to ultrasound examination, women undergo CTG - cardiotocography. This method allows specialists to identify serious pathologies in unborn children and take the necessary measures in a timely manner. What is CTG and what is it prescribed for? What important information do doctors receive from this study?

Cardiotocography is the most acceptable way to assess the condition of a child who has not yet been born. During the study, a graphical registration of uterine activity and the frequency of fetal heart contractions is carried out. Experts evaluate the results obtained and draw appropriate conclusions.

The essence of cardiotocography

The study is carried out using a special device called a cardiotocograph. An ultrasonic sensor is designed to record heartbeats. Uterine activity is recorded by strain gauges.

All information is recorded on the cardiotocogram. It is a graph with two lines. The first curve is a tachogram. It is used to evaluate the work of the child's heart. The second curve on the graph is the histogram. It is used to assess the change in the force of contraction of the uterus.

CTG during pregnancy and delivery

Cardiotocography is done during pregnancy. The strain gauge is installed in the area of the fundus of the uterus. It is not placed on the lateral surfaces of the abdomen. The ultrasonic transducer is then placed. Its location is determined depending on the presentation and maturity of the fetus.

For cephalic presentation and full-term pregnancy, the sensor is placed slightly below the navel. As a rule, only in this place is it possible to receive a stable audio signal. In breech presentation, the ultrasound sensor is placed closer to the bottom of the uterus, and in premature pregnancy, closer to the pubic joint.

Cardiotocography is also done during delivery. Heartbeats are recorded using a special electrode. It is introduced into the presenting part of the fetus. Uterine contractions are fixed with a catheter inserted into the organ cavity.

Indications for cardiotocography

The first study of women in the position takes place at about the 32nd week of pregnancy. If the results are good, then repeated CTGs are prescribed 1 time in 7-10 days. There is no point in doing research more often.

If the period of bearing a child proceeds with complications, then cardiotocography is performed with any changes in the condition of a pregnant woman. Indications for frequent monitoring:

miscarriages and premature birth that were in the past;
the woman has any chronic diseases;
gestosis (complication during pregnancy, which is manifested by increased blood pressure, edema, convulsions);
lack of water or polyhydramnios (decrease or increase in the amount of amniotic fluid);
developmental defects in a child;
multiple pregnancy.

When labor begins, doctors conduct an initial cardiotocographic study. If its results are favorable, then repeated CTG in the first period is done every 3 hours. In the second stage of labor, constant monitoring is carried out.

If, in the course of the initial study, made at the beginning of labor, specialists receive unfavorable data, then continuous monitoring begins immediately. Monitoring is carried out before a decision is made to conduct a caesarean section or to refuse it.

Sensors of the cardiotocography apparatus on the belly of a pregnant woman

Basic rules for conducting CTG

The posture of pregnant women at the time of the study is an important factor influencing the results. Cardiotocography is recommended with the patient on the left side. A sitting position is also allowed. Lying on your back is not worth carrying out cardiotocography. The results will be unreliable due to the compression of the blood vessels by the uterus.

Another rule of CTG is the use of a special acoustic gel. It is applied to a sensor that records the work of the baby's heart. Sometimes the gel is not treated with the sensor, but the belly of the pregnant woman. This is not considered a bug. But the strain gauge must be left dry. The gel is also not applied to the place of its fixation.

The duration of cardiotocography plays an important role. Short-term recordings are undesirable, because in such cases there is a high probability of obtaining false results. The duration of the cardiotocography should be about 20 minutes. If the study shows pathological or disturbing rhythms, then it is performed within 40 minutes.

During childbirth, the duration of cardiotocography should be at least 20 minutes. If suspicious signs are found, then the study is not stopped. The recording is continued until a decision is made on the further tactics of labor management.

Assessment of cardiac activity

During the study of the cardiotocogram, all parameters that characterize the work of the fetal heart are considered. Subject to assessment:

deceleration and acceleration;
basal rhythm;
variability of the basal rhythm.

Deceleration and acceleration

When evaluating the cardiotocogram, manifestations of irregularity of the heart are necessarily analyzed. They are called decelerations and accelerations. Deceleration is a slowing down of the heart by 15 beats per minute for 15 or more seconds. Acceleration is also called an increase in heart rate.

Normally, on the cardiotocogram, manifestations of a slowdown in the work of the heart should be absent. The presence of sporadic (unpredictable) peak-like deceleration after acceleration with a depth of up to 30 beats per minute and a duration of no more than 20 seconds is allowed. Accelerations in response to fetal movements should be at least 4 for 20 minutes.

Basal rhythm

This term refers to the average heart rate for a specific time period without taking into account decelerations (decreases in heart rate) and accelerations (increases in heart rate). An indicator equal to 120-160 beats per minute is considered normal.

Sometimes deviations come to light:

Decreased basal rhythm. An average heart rate of 100-120 beats per minute is a sign of moderate bradycardia. A very small basal rhythm (less than 100 beats per minute) indicates the presence of severe bradycardia.
Increased basal rhythm. If the indicator is 160-180 beats per minute, then experts talk about mild tachycardia. If the basal rhythm is higher than 180 beats per minute, then this indicates a pronounced tachycardia.

Basal rhythm variability

This indicator, assessed by cardiotocography, consists of several components. However, experts pay attention mainly to the amplitude and frequency of oscillations (deviations of heart rate from the average basal level).

The amplitude of a particular oscillation is the distance between the peaks of the upper and lower wave. This indicator is assessed using horizontal lines. They are applied to registration paper every 5 beats per minute. For example, if the peaks of the upper and lower teeth of the oscillation are located on opposite adjacent lines, then the amplitude is 5 beats per minute. Normally, the oscillation amplitude is 6-25 beats.

Oscillation frequency - the number of similar basal frequency oscillations that occur in 1 minute. The indicator is calculated by the number of heart rate peaks. The oscillation frequency is normally more than 6 cycles per minute.

CTG results: possible pathologies

If most of the indicators are outside the physiological norm, then doctors diagnose intrauterine fetal hypoxia, that is, oxygen starvation. This condition is quite dangerous. Due to the lack of a vital element, the metabolism in the child's body is disrupted. If a lack of oxygen is detected, doctors record CTG daily.

Hypoxia can be severe. For a cardiotocogram reflecting this pathology, the following indicators are characteristic:

basal rhythm more than 180 or less than 100 beats per minute;
no acceleration for 30 minutes;
the presence of pronounced variable decelerations;
the amplitude of the oscillations is less than 3 beats;
the number of oscillations is less than 3 cycles per minute.

Severe hypoxia indicates that intrauterine fetal death may occur suddenly. When diagnosing this pathology, doctors perform an immediate delivery. Timely detection of hypoxia can save a child's life.

Sometimes, with cardiotocography, only bradycardia or tachycardia is detected. No other changes are detected. In such cases, this change in cardiac activity does not indicate the presence of hypoxia. The unborn child may have some kind of congenital heart disease.

Is research dangerous?

Whether CTG is harmful is a question that arises in almost all pregnant women. In this regard, it should be noted that there are no contraindications to CTG. The study is assigned to absolutely all pregnant women and women in labor. It does not pose a serious danger to the expectant mother and child. In addition, cardiotocography is a painless procedure.

Although the study is safe, complications sometimes arise. They appear only after internal cardiotocography performed when the membranes are ruptured. However, negative consequences are extremely rare. The fact is that the specialists conducting the research follow the rules of asepsis and antiseptics.

Cardiotocography is a highly informative diagnostic method. If signs of well-being come to light, then nothing threatens the child in the near future. The results remain valid for 7-10 days. If the cardiotocogram does not indicate the well-being of the fetus, then the child may have hypoxia. In such cases, any outcome options are possible that cannot be predicted using CTG. It all depends on the doctor who decides on the further tactics of pregnancy management.

Cardiotocography is a test that is only performed on pregnant women. The procedure is completely harmless to the baby and, in general, does not affect the course of pregnancy. It is prescribed to assess the cardiac activity of the fetus and identify possible violations, including such a dangerous condition as hypoxia - a lack of oxygen.

To properly prepare for the study, you need to know what CTG is during pregnancy and how it is done.

KTG - what is it

On routine inspection for pregnant women, the baby's heart rate is measured with an obstetric stethoscope. However, this method is not enough to determine any cardiac disorders or fetal hypoxia. If such pathologies are suspected, the doctor directs the woman for a more complete examination of the baby's heart - CTG.

Pregnant women are usually interested in each procedure, as they worry about the unborn child. Accordingly, it is a normal desire of every mother who receives such a referral to learn about CTG during pregnancy - what it is and why.

With the help of cardiotocography, the heart rate of the child is measured, taking into account the effect on him of the uterine contractions. And also fix his movements in the womb. Evaluation of all parameters allows you to determine how the child reacts to a particular stimulus.

The procedure is most indicative from the 32nd week of pregnancy. If there are indications, it can be done earlier - from the 28th week, but the result in this case should be evaluated in conjunction with other studies - dopplerography and ultrasound. This is due to the fact that on early dates the baby's heartbeat may not be heard by the device. Among other things, in the third trimester, the fetus develops distinct phases of sleep and activity, which is also important.

If the pregnancy is proceeding normally, CTG can be prescribed 2-3 times for the entire period before delivery. If you suspect hypoxia or other heart disorders of the child, the study is carried out every 7 to 10 days. If pathology is detected according to previous results, as well as when in a hospital for any indication, the measurement is performed daily.

During childbirth, CTG is a mandatory procedure. It is performed every 3 hours if the period of contractions is proceeding normally. In cases where any complications are identified, the doctor prescribes CTG additionally, so that, if necessary, take timely measures for emergency delivery.

How is the procedure carried out

CTG lasts from 20 to 40 minutes, depending on the timing and initial results. During childbirth, the study is carried out during 5 contractions. The measuring device is equipped with two sensors:

Ultrasound, as with a conventional ultrasound, measures the heart rate of the child.
Strain gauge - captures the contractions of the uterus.

Older models are additionally equipped with a remote control with a button that must be pressed when a woman senses movement. Modern devices record the child's movements on their own.

The study is carried out in a supine position, sitting or reclining. It is not recommended to lie horizontally on your back, as this can compress the umbilical cord, which negatively affects the child and, as a result, the results. The sensors are attached to the abdomen using special belts. Ultrasound - in the place where the heart of the child is best heard, and strain gauge - in the upper abdomen.

What CTG shows depends not only on the real state of the child, but also on other factors. Best time frames to explore:

in the morning - from 9 am to 2 pm;
in the evening - from 19 to 24 hours.

If CTG is carried out at a different time, and at the same time any deviations are revealed, before drawing conclusions, you need to repeat the procedure, taking into account this condition.

How to prepare

Special preparation for CTG is not required. You don't need to take anything with you to the cardiotocography, except for a diaper, which you will need to put on the couch where the study will be carried out. It is advisable not to overeat before the procedure, but you should not be hungry either. Optimally, if the meal was taken 1.5 - 2 hours before the meal. The fact is that the baby reacts to changes in the amount of glucose in the mother's blood, and this can blur the results. As a last resort, if the woman is hungry, you can eat a chocolate bar.

It is imperative to take into account that during pregnancy, the urge to go to the toilet occurs quite often, so before CTG you need to empty bladder so you don't have to interrupt the study.

When CTG is done, stress and other emotional upheavals can negatively affect the results, so you need to go to the procedure in a calm state. The baby is very sensitive to changes in the mother's mood and may be overly active.

Decoding the results

The conclusion on the CTG schedule is based on the following parameters:

Basal heart rate is the average fetal heart rate. This parameter is normally 120 - 160 beats / min.
Heart rate variability is the number of amplitude changes in the basal heart rate over a period of time. The norm of CTG is from 6 oscillations (changes up or down) in 1 minute.
Acceleration - an increase in heart rate by 15 beats / min or more for 15 seconds. Their number is estimated. More than 2 accelerations in 10 minutes are considered the norm.
Deceleration - a decrease in heart rate by 15 beats / min or more for 15 seconds. In normal condition, the fetus should be absent or insignificant and rare.
The amplitude of heart rate oscillations is the average value of deviations from the basal heart rate. Should be within 5 - 25 beats / min.

For the convenience of evaluating the results, it is customary to evaluate each of the parameters from 0 to 2 points. The higher the number, the better. The scores are added together to get the overall research score.

Depending on the number obtained, the results are interpreted as follows:

8 - 10 points. Normal indicators, no violations were found.
6 - 7 points. Found signs of fetal hypoxia. To clarify the diagnosis, it is necessary to repeat CTG and undergo additional examination - Doppler and ultrasound.
5 points or less. Immediate hospitalization is required, as serious cardiac abnormalities have been identified. In a hospital setting, the cause of the deviations is determined, intensive therapy is carried out and, if necessary, urgent delivery.

The scoring of the study is carried out by the attending physician, then the result is reported to the patient. To obtain reliable data, it is important to observe the conditions for time and food intake. And you also need to understand whether the child is awake at the time of the procedure. Usually, pregnant women themselves can determine this without much difficulty, based on their feelings.

If the fetus is in the sleep phase, CTG will definitely be "bad", which can mislead the doctor and the woman about the baby's health.

The cardiotocogram is an important and revealing study. However, it must be remembered that it is impossible to draw final conclusions based on the results of CTG alone. The assessment of the condition of the child and his cardiac activity is carried out in a complex with other planned and additional examinations.

Self-assessment of the results will help you orient yourself and allow you to see the big picture. But decoding must necessarily be carried out by a doctor, based on his experience and knowledge.

Cardiotocography is an important part of a comprehensive assessment of the condition of the fetus, along with ultrasound and pre-measurement. With this procedure, doctors record uterine contractions and the heartbeat of an unborn baby. KTG allows you to identify any problems and start solving them in a timely manner.

Doctors who monitor the development of the fetus give women directions for cardiotocography from the 30th week, but they can be issued earlier if there are certain indications for CTG during pregnancy.

Usually, the fair sex is advised to undergo CTG several times during pregnancy, namely during the third trimester 2 times. If the pregnancy is accompanied by complications, then medical workers may prescribe additional research.

CTG is also performed during childbirth. This is required in order to determine the general condition of the baby and decide on the further management of the birth process. Special monitoring is required for babies who, according to the results of an ultrasound scan, have an umbilical cord entanglement.

How is CTG done during pregnancy?

Cardiotocography is a safe procedure. It will not harm either the mother or the child.

The question of how CTG is done during pregnancy is of interest to women who have never undergone this procedure. She is absolutely fearless. The doctor asks the woman to take a recumbent or reclining position. You just need to relax and sit comfortably on your back. Several sensors will be attached to the tummy:

Ultrasonic, which records the baby's heartbeat;
Strain gauge (pressure sensor), with which the contractions of the uterus are recorded.

Cardiotocography is performed in a phase characterized by fetal activity. The doctor makes the appointment within 30-60 minutes. All data in the form of graphs is recorded by a special device on a paper tape.

A woman should not forget about preparation for CTG during pregnancy. It is recommended to have a good sleep before the procedure, tune in, forget about all the problems and fears and have a snack before it. You can eat a chocolate bar before cardiotocography so that the child does not sleep, but is more active. Before starting the study, you should definitely go to the toilet, since the procedure takes a long time.

Decoding CTG during pregnancy

The doctor can show the results of CTG during pregnancy on a paper tape on which graphs are shown, or say, naming the number of points scored.

Deciphering CTG during pregnancy is not an easy matter. It's good if the charts are absolutely not suspicious. Then the doctor and the expectant mother will not have to worry about anything. However, there are different cases in life. CTG results can be alarming. In such a situation, it is very important not to be mistaken. Any decision must be carefully thought out by the doctor, because every action and word affects the child.

Here illustrative example taken from life: a young doctor, who had not yet gained experience, did not like the results of cardiotocography of one patient. He informed the pregnant woman about his concerns, but she categorically did not believe the results of CTG of the fetus during pregnancy. One can easily imagine how the woman felt at that moment. The specialist called “ ambulance”, Because he was worried about the patient's condition and the life of the fetus. In the maternity hospital, the pathology department later revealed that the pregnant woman had absolutely no abnormalities. With what mood will this patient come next to the antenatal clinic?

It would be nice if the expectant mother could learn to interpret in general terms the results of cardiotocography. So it would be possible to avoid unnecessary waste of nerves and collisions with the above incident.

When decoding cardiotocography and making a diagnosis, many factors need to be taken into account, because the results are influenced by weather conditions, the mood of a pregnant woman, sleep or active wakefulness of children. Based on the results of poor CTG during pregnancy, it is not recommended to draw conclusions about the condition of the baby in the tummy, because even a perfectly healthy baby may have "suspicious" schedules.

When decoding a cardiotocogram, doctors take into account several basic parameters: basal rhythm, amplitude, as well as the frequency of deviations from it, decrease and increase in heart rate. Each parameter is awarded 0-2 points. At the final stage, the points obtained are added up, and the state of the fetus is assessed by their sum:

8-10 points – CTG norm during pregnancy;
6-7 points indicate possible early signs of fetal distress. The doctor may prescribe additional research;
5 or less points are an indicator that a pregnant woman urgently needs hospitalization and care.

Heart rate assessment

The basal heart rate of the fetus should be 110-160 beats per minute. The graph clearly shows that ups and downs alternate. However, the physician is not interested in the minimum or maximum values. He estimates the average.

A woman can independently evaluate what CTG shows during pregnancy. To do this, you need to move the printout at arm's length and drag your finger over the graph, as if drawing it in a straight line. The level to which the line on the vertical axis will correspond and will be the basal rhythm.

Study of teeth and teeth

The next parameter that doctors evaluate is the variability of the child's heartbeats. Having determined the basal rhythm, you can begin to study the frequency and amplitude of deviations from this rhythm.

The graph clearly shows that the curves have many small teeth and several large teeth. Small teeth show deviations from the basal rhythm. It is desirable that there are no more than 6 of them per minute - this is the norm of CTG at 32-39 weeks of pregnancy. However, counting the number of small teeth is not easy. Doctors often assess the amplitude of deviations - changes in the height of the teeth on average, which should normally be 11-25 beats per minute.

Doctors may not like it if the change in tooth height is 0-10 beats per minute. However, this can be quite normal if the baby feels comfortable in the mother's tummy and is sleeping or the gestational age does not exceed 28 weeks. When the estimated figure of 25 beats per minute is exceeded, healthcare providers begin to suspect the presence of an umbilical cord entanglement or fetal hypoxia.

Assessment of increases and decreases

When assessing the increase and decrease in CTG at 32-38 weeks of pregnancy, you should pay attention to the large teeth shown in the graph. Doctors, doing cardiotocography on old devices, ask pregnant women to press a special button when the baby moves. Modern models no longer require this. They themselves are able to register the activity of the fetus. When the baby pushes, his heart beats faster for a few seconds. This will be represented on the graph as a large tooth growing upward. This is called an increase. If there are at least 2 of them on the chart in a 10-minute period, then this will be considered a good sign.

Increases may or may not have been identified for research. Don't panic ahead of time because of this. Perhaps the baby has not yet woken up.

Reductions - this is the complete opposite of the increase. On CTG chart for 35-39 weeks of pregnancy, they look like teeth growing down. There is no cause for concern if the increase on the graph is followed by a short and shallow decrease, after which the curve returns to the level of the basal rhythm. High-amplitude cuts can alert you. However, before making a conclusion, you should pay attention to the 2nd graph on the printout. Contractions of the uterus, which are noted on it, can affect the occurrence of contractions.

In conclusion, it should be noted that the CTG method has several undeniable advantages. Firstly, thanks to this procedure, you can find out about the condition of the fetus and the nature generic activity, quickly identify existing problems and find ways to solve them, and secondly, when CTG is done during pregnancy, there are no unpleasant sensations. The procedure is completely safe for the mother and fetus. Thus, if expectant mothers are worried about whether CTG is harmful during pregnancy, then the answer is always unambiguous - it is harmless.

Many pregnant women are concerned about the question: CTG of the fetus - what is it? This is cardiotocography, which is safe method examination of the fetus during pregnancy. Thanks to this method, doctors are able to determine the assimilation of oxygen, physical endurance in the form of heart contractions and their changes.

Doctors perform CTG of the fetus during pregnancy, as well as during childbirth, when the child passes through the birth canal. And the results of CTG show how the child's condition is assessed.

How fetal CTG is done

What does fetal CTG mean? For women who are experiencing this procedure for the first time, information about it will be useful and interesting. First of all, you need to understand how fetal CTG is done. During the examination of the fetal heart rate, ultrasound sensors are placed on the woman's abdomen.

The signal generated by the sensor is sent to the baby's heart, and returns back with the fixation of the heartbeats on the heart monitor. Indicators of CTG are calculated by the number of beats per minute. All changes are recorded in digital graphics.

The study should not be carried out immediately after a meal or, conversely, on an empty stomach, since sugar levels can distort the results. Also, during the diagnosis, a woman should feel comfortable.

Why do you need CTG of the fetus

In addition to the fact that CTG allows obtaining data on the fetal heartbeat and is an extended version of the cardiogram, this type of examination also reveals other abnormalities in the development of an unborn child.

Pathologies determined by CTG include:

hypoxia;
intrauterine infections;
rapid maturation of the placenta;
placental insufficiency;
abnormalities of the cardiovascular system.

Usually, it is necessary to do CTG of the fetus only twice during pregnancy, but doctors, if they suspect a deviation in the normal course of pregnancy, may prescribe an additional examination. CTG of the fetus is normally carried out for weeks after the 30th week of pregnancy.

Decoding cardiotocography

Deciphering survey data is no less important than the survey itself. An experienced doctor can even see the initial disturbance of the fetus according to special charts, but sometimes CTG scores are set, which is more accessible and understandable information for a pregnant woman.

In any case, the expectant mother should be able to understand at least a little about the norm of cardiotocography and deviations from the norm. When decoding, the basal rhythm, amplitude, acceleration or, conversely, a reduction in heart rate are taken into account. Each parameter is determined in points from 0 to 2. And at the final stage of decoding, the points are added, and their total number determines the violation of the fetus.

If the total number of points is 5 or less, then the pregnant woman urgently needs hospitalization. If 6-7 points, then the woman undergoes mandatory additional examinations in order to exclude possible pathologies. An ultrasound scan, other studies that will determine the movement of the fetus, its activity, and sufficient placental nutrition are carried out. If there are 8-10 points, then such an indicator is the norm and indicates the normal health of the child and a well-proceeding pregnancy.

An important indicator is the basal rhythm - it should be from 110 to 160 beats. The doctor will not be interested in the maximum and minimum values on the graph. Average values are important. It is not difficult to understand the graphs on your own.

It is necessary to move the graph to the distance of an outstretched hand, draw a conditional straight line along the graph with your finger. The basal rhythm will be the line of the vertical axis, which corresponds to the level being conducted.

Variability is another indicator. It should be 5-25 strokes. If the frequency of blows is less, then this indicates a short pregnancy or that the baby is at rest. Although this may be a reason for additional examination. At a high frequency of strokes, fetal hypoxia is possible due to the entanglement of the umbilical cord.

The rhythm, the number of accelerations, decelerations are also determined, but these indicators can only be deciphered by medical workers. According to them, the indicator of the state of the fetus is determined. If this indicator is less than 0.8, then there is no need to worry about the child's condition. The procedure is completely safe, therefore expectant mother no need to worry about anything.

Cardiotocography (CTG)

While carrying a baby, any mother worries about how comfortable the baby is inside her, and tries to provide him with everything he needs for full growth and development. That is why all expectant mothers strictly undergo numerous analyzes and various studies, among which it occupies an important place during pregnancy. However, not everyone thoroughly understands the essence and importance of this study. This article describes the most popular questions related to this type of analysis.

Why do a CTG test during pregnancy?

(KGT) is performed in order to obtain data on the cardiac activity of the fetus and the frequency with which its heart beats. Also studied physical activity the child, with what frequency the genital organ contracts and how the baby reacts to the pressure exerted on it. The CTG procedure during pregnancy, in conjunction with ultrasound and dopplerometry, gives a real chance to establish any deviations from the normal gestation process, to study the reaction of the heart and blood vessels of the fetus to the contractile function of the uterus. With the help of this analysis, it is possible to determine such dangerous situations how:

oxygen starvation of the child;
intrauterine infection;
polyhydramnios or lack amniotic fluid;
placental deficiency;
unnatural structure of the heart and blood vessels in the fetus;
premature birth;
aging of the placenta and so on.

Timely clarification of all these circumstances enables the doctor to take emergency measures and correct the flow of gestation.

When is KGT done during pregnancy?

The most optimal period for this study is the third trimester of gestation, starting from about 32 weeks. This is due to the fact that by this time the child already has a fully formed cardiac contractile reflex, a relationship has been established between the activity of the heart and the baby's movements, and the "sleep-wakefulness" cycle has been defined. Of course, the study can be done earlier, but in this case, the CHT indicators during pregnancy may be unreliable.

Preparing for CTG during pregnancy

The woman does not need to prepare for the study well in advance. Two sensors will be attached to the belly of the expectant mother, registering the activity of the uterus, fetus and the baby's heartbeat. A prerequisite is a comfortable position of the woman's body, no matter whether she is sitting or lying down. A device with a button is put into the hands of a pregnant woman, on which she must press every time the baby begins to move.

KGT rate during pregnancy

Let's make a reservation right away that the data obtained in this way cannot serve as a serious basis for confirming a particular diagnosis. To obtain reliable information, the study must be carried out several times. There are certain standards for examining CTG during pregnancy, for example:

Depending on the data obtained, a conclusion is drawn up on the condition of the fetus, which is guided by a generally accepted scale or a 10-point system. In the event that CTG is bad during pregnancy, the doctor may well prescribe a woman to stimulate labor ahead of time.

Is CHT harmful during pregnancy?

This is perhaps the most exciting question for expectant mothers. This research cannot do any harm to the baby, in contrast to the refusal to carry it out. KGT can be done as needed, even every day.
