You can imagine that
The fetus of the atrium beats more than 400 times in 1 minute,
(three times the normal fetal atrial rate)
How critical is the situation?
Recently
Under the emergency linkage of multiple departments of Xiamen Maternal and Child Health Hospital,
A rare atrial fluttering baby was born safely!
Not long ago, Ms. Li (pseudonym) came to the Obstetrics and Gynecology Special Needs Clinic of Xiamen Maternal and Child Health Hospital for routine obstetric examination. During fetal heart rate monitoring, the obstetrician keenly found that the full-term baby's heart rate was too fast, judging that there may be serious risks. Ultrasound medicine doctors soon discovered that the fetus was not simply too fast heart rate, but had a room flutter!

What is Room Flutter?
In layman's terms, normal heart beat is very regular and coordinated, the atrium jumps a little followed by a ventricular beat so circulating, the fetal atrial rate has reached 450 times / min at this time, the ventricular rate has reached 225 times / min, showing a "2:1 downward transmission", immediately judged as arrhythmia, and the atrial rate has reached 3 times the normal fetal atrial rate.
The situation was 100,000 urgent, and the hospital quickly opened an emergency rescue channel. Obstetrics, operating room, neonatology and other related departments of rapid linkage, tacit cooperation... With a loud cry, a baby with a full apogar (newborn rating) was born!
The baby's electrocardiogram once again confirmed the diagnosis of prenatal ultrasound, the baby's atrium fluttering, and then a few hours later, the consequences will be unimaginable!
How to judge fetal arrhythmias?
Normal fetal heartbeat rhythm is regular, with a heart rate of 110-160 beats/min, with a difference of 5-10 beats/min within 1 minute. Arrhythmias that are too fast, too slow, or the heart that doesn't beat regularly are arrhythmias. Severe arrhythmias can lead to fetal heart failure and even life-threatening.
Fetal arrhythmia needs to observe the movement of the heart through fetal echocardiography, the beating order of the atrial ventricles, the direction of blood flow in the heart, etc. to make a comprehensive diagnosis, and it can also find out whether the fetus has congenital heart structural abnormalities, whether there is pericardial effusion, pleural effusion, etc., which are the key to affecting the fetal treatment plan and prognosis.
Duration of ultrasound during pregnancy:
1. 7-9 weeks pregnant
At this time, ultrasound is helpful in judging whether it is an intrauterine pregnancy, observing whether there is a primitive heart canal beat, observing the number of gestational sacs, and so on. However, if there is no abnormal situation such as vaginal bleeding and abdominal pain at this stage, it is generally recommended to have the first obstetric ultrasound examination for 11-13 + 6 weeks.
2. Pregnancy 11-13+ 6 weeks
It is what we often call the NT ultrasound examination stage, at this time through ultrasound can measure the diameter of the head and buttocks, that is, the distance from the top of the fetal head to the bottom of the buttocks, to determine the accurate gestational age, to provide standards for the future growth and development of the fetus.
In addition, the NT value can also be measured, that is, the transparent layer of the skin of the fetal neck, combined with the gestational age to determine whether the transparent layer of the fetal neck is thickened, this examination can be early screening for fetal chromosomal diseases and more obvious fetal malformations.
3. 18-24 weeks pregnant
At this time, the structure of the fetal organs and the amount of amniotic fluid are most suitable for ultrasonography, and the detection rate of fetal abnormalities is high.
Through the fetal structure screening at this stage, the size of the fetus and the development of fetal head, nose and lips, spine, heart, lungs, gastrointestinal tract, kidneys, bladder, external genitalia, limbs, placenta, and amniotic fluid can be observed.
4. 30-32 weeks pregnant
The ultrasound examination during this period focuses on observing various growth indicators, measuring the double top diameter, head circumference, femur length and abdominal circumference of the fetus, observing whether the growth and development of the fetus is consistent with the gestational week, understanding whether there is developmental delay or huge fetus caused by high-risk diseases such as hypertension, cholestasis, diabetes, etc. during pregnancy, and screening for fetal development abnormalities that occur in the second and third trimesters of pregnancy.
5. Before childbirth
Ultrasound during this period focuses on determining the position and maturity of the placenta, the position of the umbilical cord and amniotic fluid, estimating the size of the fetus, and judging the safety of the fetus through umbilical blood flow. The doctor's understanding of these conditions is very important for the safe delivery of the baby and the health and safety of the mother.
If there is abdominal pain, vaginal bleeding, frequent or decreased fetal movements, uneven fetal development and unclear fetal position during pregnancy, the number of examinations should be increased as appropriate according to the doctor's examination.
Remind mothers-to-be
On-time obstetric examinations, regular fetal heart rate monitoring,
Usually pay more attention to the fetal movement,
When the baby's fetal movement is abnormal, it is necessary to consult a doctor in time.
