Slow heart rate It is important to note that bradycardia is more dangerous to the fetus than tachycardia, because it may be a sign of fetal distress. Creating short dynamic sounds These methods, if they help to increase the heart rate quickly, show that the fetus is still healthy. Put your finger through the cervix, press on the head of the fetus, for the lateral position. ![]() During this process, if there are abnormal signs of heart failure, the heart rate slows down, most doctors will usually make the fetal heart beat faster by the following ways: Gently shake the mother's belly. A sudden rapid increase in fetal heart rate occurs many times during different periods of labor and delivery. The reason why the heart rate tends to increase rapidly is because the fetus needs enough oxygen to breathe.

The average fetal heart rate can fluctuate from 120-160 beats/minute but the heart rate can increase as fast as 180 times/minute if the baby is moving a lot. At this time, the fetal heart can pump about 24 liters of blood per day. By the end of week 16, the fetal heart is structurally complete and can function as a normal heart.

When is the fetal heart heard?Įquipment serving ultrasound from the outside will support the doctor to measure and monitor the fetal heart rate. Normally, the fetal heart beats between 120 and 160 times per minute. From the next weeks of pregnancy until the baby is born, the fetal heart rate continues to increase in size and volume. At this time, the heart is complete in terms of structure and assumes its functions. By the 16th week, you can already pump blood with an amount of about 24 liters / day and this amount will continue to increase with the development of the baby. At the 14th week of pregnancy, the fetal heart beats more clearly. Fetal heart begins to beat slightly at 11 weeks of pregnancy and by about 12 weeks it is almost complete. Fetal heart rate continues to increase until it peaks around week 9, between 140–170 beats per minute for boys and girls. Beats per minute start at 90–110 beats/min and increase every day. You can even see and measure the flashing lights on the ultrasound machine. ![]() By the 7th week, the fetal heart rate increases and begins to divide into the left and right chambers. By the end of the 5th week of pregnancy, this is an important milestone, if the fetus sees the heart, it shows that it has risen into a living germ.
