How many weeks of pregnancy should cardiac ultrasound be performed

Everyone knows that pregnant women need to do various prenatal examinations during pregnancy. Only in this way can the normal growth and development of the fetus be guaranteed. In addition, a cardiac ultrasound is required in the early stages of pregnancy. The cardiac ultrasound is not only used to monitor the heart of the pregnant woman, but also to monitor the heart rate of the fetus. This kind of examination is a must. So, when is the best time to do a cardiac ultrasound?

How much does a cardiac ultrasound cost?

The specific examination items during pregnancy need to be determined according to the number of weeks or months of gestation. You cannot do whatever examination you want at any time. For some examinations, doctors will recommend not to do them once you miss the best time. So, in which week of pregnancy can pregnant women do cardiac ultrasound?

When a pregnant woman should have a cardiac ultrasound examination depends on the development of the fetus. Only when the fetus develops to a certain stage and the heart image can be clearly displayed, pregnant women are suitable for cardiac color ultrasound. On the contrary, if the fetus is too small and the internal structure of the heart has not developed to a certain level, or if the pregnant woman is in the early stages of pregnancy, it is impossible to accurately detect fetal heart problems.

In addition, in the late pregnancy, the amniotic fluid in the pregnant woman's uterus becomes less, the fetal movement is restricted, and the fetal bones block the sound shadow at this time, making cardiac color Doppler ultrasound difficult.

Therefore, choosing the right time to check cardiac ultrasound can get the most accurate results. Generally speaking, it is best for pregnant women to have a cardiac ultrasound between the 20th and 24th weeks of pregnancy. At this time, the fetal development level has reached the requirements for examination, and the examination results are relatively accurate.
