What happens if my baby’s heart rate is abnormal?
Usually, abnormal heart rhythms have little or no effect on the fetus. In rare cases, they can cause heart failure in utero and at birth. Bradycardia can be a sign of distress for the fetus. When it occurs earlier in pregnancy, it may be the result of other problems and may lead to heart failure and even fetal death.
Can you see Down syndrome on ultrasound?
An ultrasound can detect fluid at the back of a fetus’s neck, which sometimes indicates Down syndrome. The ultrasound test is called measurement of nuchal translucency. During the first trimester, this combined method results in more effective or comparable detection rates than methods used during the second trimester.

What are soft signs of Down’s syndrome?
The most commonly studied soft markers of aneuploidy include a thickened nuchal fold, long bones shortening, mild fetal pyelectasis, echogenic bowel, echogenic intracardiac focus, FMF angle > 90 degrees, pathologic velocity of Ductus venosus and choroid plexus cyst.
What are high markers for Down syndrome?
Increased nuchal fold (P < 0.001) and structural malformation (P < 0.001) were the markers most associated with Down syndrome. The presence of one marker increased the relative risk 10.5-fold, while the presence of two or more markers increased the risk 13.5-fold.

The cut off is 1 in 150. This means that if your screening test results show a risk of between 1 in 2 to 1 in 150 that the baby has Down’s syndrome, this is classified as a higher risk result. If the results show a risk of 1 in 151 or more, this is classified as a lower risk result.
Is it normal for fetal heart rate to go up and down?
