Pregnant: when is the heart beating
-
If you are pregnant, you want to see the baby's heart beating as soon as possible. This can be done by means of an ultrasound at six weeks of pregnancy, and by means of a doptone at twelve weeks of pregnancy. Yet the heart beats earlier than six weeks of pregnancy. The heart is still very primitive in the beginning.
Development of the heart
-
The body is made up of cells, many cells. A fertilized egg is one cell that quickly divides into two, four, eight, etc. A cell can move, grow and divide. Some cells grow into heart cells, others into brain cells or other types of cells. A number of the same cells together form one organ. The hereditary material of every cell consists of DNA. The DNA sends out molecular signals. This ensures that a cell does or does not produce certain proteins. The proteins determine what a cell can or cannot do.
When can the heart be seen on an ultrasound?
-
Every pregnant woman is looking forward to it: seeing the baby's heart beating. An ultrasound can show the heart beating with a pregnancy of six weeks (four weeks after conception). With an internal ultrasound it is sometimes possible to see the heart beating at 5.5 weeks.

Hearing the heart with the doptone
-
A doptone works with sound vibrations. It captures the vibrations of the heart and converts it into a sound signal. This is slightly different from an echo: here the vibrations are converted into images.
The heart is not beating
-
If the midwife cannot find a beating heart with the doptone, she will continue the search with an ultrasound. If the ultrasound also does not show a beating heart, she will send the pregnant woman to the gynecologist. He will examine the woman further. In some cases, the gynecologist will be able to find the beating heart. In other cases, something is wrong with the baby.
