The heart is the power pump of a normal person and an important organ needed by everyone who needs a normal life. As is well known, the fetal heart has a certain development time and process, and the development of the fetal heart also varies slightly during different stages of pregnancy. So, when is the fetal heart formed?
The fetus is constantly growing in the mother's womb. Under normal circumstances, at 17 weeks, the fetal heart development is almost complete, with strong heartbeats of around 145 beats per minute. The embryonic form of gums appears. The arms grow faster than the legs, and the appearance of elbow joints begins to appear.
Fetal cardiac ultrasound examination is better performed between 20-24 weeks of pregnancy, but for those with thick abdominal walls and poor fetal position, it can be performed around 20 weeks for clearer images. Before 20 weeks of examination, due to the small size of the fetus and incomplete development of the heart structure, certain lesions may not be clearly displayed.
The normal growth and development of the fetus is the greatest wish of every pregnant woman. However, due to various factors, the fetus has developed deformities. Fetal malformations can occur in any part of the body, and various types of malformations can also occur. Generally speaking, B-ultrasound examination can detect fetal abnormalities early, but it can only detect and determine cardiac abnormalities through B-ultrasound when the fetus has grown large enough.
