Fetal heart check in late pregnancy

This study uses a special ultrasound method (speckle tracking echocardiography) to look for early signs that a twin pregnancy may have impaired fetal growth. It may help clinicians detect problems earlier and better understand how twin babies’ hearts and growth are affected.

This study uses ultrasound to look at blood flow patterns in the heart and major blood vessels of babies who are smaller than expected (fetal growth restriction). It will compare these patterns to those in normally growing babies to see how they change as other growth measurements change.

This study tests whether a routine heart recording test (ECG) can capture fetal (baby) heart activity during late pregnancy. It may help researchers find simpler ways to monitor baby heart rhythm without special equipment.

This study uses automated ultrasound measurements to track how a baby’s heart is working during pregnancy. It compares babies who have a specific congenital heart problem with babies without it, to understand what ultrasound can detect.

This study uses ultrasound to look for birth defects in babies during the second and third trimesters of pregnancy. It may help understand how well ultrasound can detect problems in healthy pregnancies.

This study looks at how to measure and understand an unborn baby’s heart rhythm using special ultrasound/electrical testing. It may help doctors better evaluate abnormal or possibly abnormal fetal heart rates.
