The rate of palpitation of the fetus varies throughout the gestation period:
As can be seen, the heartbeat of the baby during the intrauterine development varies dramatically, it is associated with the development of the autonomic nervous system.
Determination of fetal heart rate in pregnancy it is very important, because, according to the heart rate indicators, it is possible to identify certain deviations, and this, in turn, contributes to the timely appointment of treatment, which allows you to eliminate the cause of changes in the fetal heartbeat.
It is clear that the heart rate to 100 and over 200 beats per minute at any period of pregnancy should cause serious concern. An undeveloped pregnancy is indicated by the absence of a heartbeat embryo, whose length is more than 8 mm. The exact diagnosis can be made only on the basis of the results of repeated ultrasound examination, which is carried out in a week.
Detection of fetal heartbeat
You can detect the fetal heartbeat after five weeks of pregnancy with transvaginal ultrasound. Transvaginal ultrasound is performed by inserting the sensor into the vagina. After the seventh week of pregnancy, the baby's heartbeat can be determined with the help of an ordinary ultrasound-transabdominal, that is, with the location of the sensor, directly on the abdomen.
It is believed that the heart of the fetus beats almost twice as fast as the heart of the future mother.
In the second and third trimesters of pregnancy, the norm of heart beat is 140-160 beats per minute, the rhythm of contractions is determined. Palpitation of the fetus in many respects depends on the way of life of the future mother, especially, in the late stages of pregnancy.
All pregnant women who are on the register are being examined by CTG. What are the results of cardiotography?
CTG is a combination of palpitation of the fetus and uterine contractions. The results of this study can talk about a lot, namely, it is estimated:
The heart rate of more than 160 beats per minute may indicate a poor intake of oxygen. This condition is called tachycardia. Due to deterioration of the fetus, the heartbeat can reach less than 120 beats per minute, this condition is called bradycardia
