You can even see and measure this flicker of light on an ultrasound. The beats per minute bpm start at a slow 90 to bpm and increase daily. They continue to increase until they peak around week 9 , between and bpm for boys and girls alike. Still, you can find lots of forum topics across the web on this subject.
Though many women swear heart rate clued them in, the overall results are mixed at best. For example, on NetMums. Some even shared that their boys actually had higher heart rates, while others shared that their girls had lower beats per minute.
In a study published by Fetal Diagnosis and Therapy , researchers examined sonograms from women who were all under 14 weeks gestation. By this point, only women still met their study criteria. Of these pregnancies, were revealed to be girls, while were revealed to be boys. Did heart rate help predict gender? The average heart rate for baby boys in the first trimester was In other words, this myth is busted.
There was not a significant difference between male and female heart rates during early pregnancy. In most cases, little girls carry an XX pattern of genetic information, while little boys carry an XY. In fact, boys and girls look relatively the same four to six weeks after gestation. Unless there are signs that the fetus is in trouble, pre-term delivery or Cesarean section is not necessary.
Cesarean section may be necessary for obstetrical reasons, however. It is recommended that mothers deliver in a hospital that has immediate access to a specialized neonatal intensive care unit NICU , with a pediatric cardiologist and other specialists present. You will most likely be able to hold your baby after delivery. Neonatologists will be present to assess your baby and start treatment if necessary, or bring him or her to the neonatal intensive care unit NICU. In most cases, your newborn will receive medications to regulate the heartbeat.
In some cases of severe bradycardia, medication alone is not effective and a pacemaker may need to be implanted. Less commonly, open heart surgery may be necessary to correct the cause of an abnormal heartbeat-for example, by destroying the nerves that are abnormally firing impulses to the heart. In other situations, a newborn may have a structural abnormality and dysrhythmia. Can a baby's heartbeat predict their sex? Written by Amanda Barrell on August 29, Is it true?

In some situations, as a result of the fast heart rate, fluid may gather inside the baby hydrops. This can make the fast heart rate more difficult to control. In most cases we can reduce the fast heart rate by giving medication to the mother, which passes through the placenta to the baby.
Some stickers will be applied to the chest to check your heart rhythm and that it is safe to give you the medication. Usually treatment is given as an outpatient and does not need a stay in hospital. We may need to take blood samples from you to check the levels of the medication in your body to make sure that they are within the correct range. The type of treatment selected depends on a number of factors including the type of the tachycardia, how many weeks pregnant you are, and if there are signs of hydrops.
