Ever since you found out you were pregnant, one of the first milestones you can look forward to is hearing your baby's heartbeat. Fetal echocardiography is also an important method in prenatal diagnosis for pregnant women.
1. When is the fetal heart?
During fetal development, the heart begins to form quite clearly and beat around 22 days after conception, often before the mother realizes she is pregnant. Fetal heartbeat will usually appear at 6-7 weeks of pregnancy, at this time with modern ultrasound techniques, we can hear the fetal heartbeat. However, in many cases, it is not until about 8 - 10 weeks of pregnancy that the fetal heartbeat can be heard, this depends on the menstrual cycle as well as the development of the embryo. During this stage, the heart develops from a simple tube shape then twists and divides, eventually forming the four chambers and heart valves (which open and close blood to release blood from the heart to all over the baby's body). From the 20th week onwards, the fetal heart beat has become strong and now just need to use normal headphones to be heard. The louder and louder the heartbeat of the fetus, the easier it is to hear, indicating that the fetus is completely healthy and developing normally.Trắc nghiệm: Bạn có hiểu đúng về dấu hiệu mang thai sớm?

Two days later, the embryo reaches the uterus and is buried in the lining for implantation. At this stage, the embryo will secrete HCG present in the urine.

During transcardiac echocardiography, cardiac activity can be determined in real-time 2D images of the uterus when the embryonic apex length is ≥ 5mm. This occurs at 5 weeks 3 days to 6 weeks 3 days of gestation, counting from the last menstrual period. After 6 weeks of gestation, spectral and color Doppler signals of pulsating blood in the fetal heart and great vessels can be detected. During the latter part of the first trimester of pregnancy, ultrasound imaging and Doppler recording can be performed transcranial.
