### What is a fetal heart strip (NST)? It is a non-invasive and safe test during pregnancy that checks the heart rate of the fetus and its reaction to natural movements. This test helps ensure that the fetus is getting enough oxygen and is healthy. ### How is the fetal heart strip done? The mother lies on her back or side on the bed. Two sensors are attached to the mother's abdomen with an elastic band: - One to record the fetal heartbeat - another to diagnose **uterine contractions** The process usually takes 20 to 40 minutes and is completely painless and safe. ### When should a fetal ECG be taken? #### ✅ Usual time: - From **32 weeks of pregnancy onwards**, when the nervous system of the fetus is more complete and can react to movements. #### ✅ In special circumstances, it may be prescribed from the 28th week, such as: - Reduction of fetal movements - Gestational diabetes High blood pressure or preeclampsia - Multiple births - History of intrauterine death - Reduction of amniotic fluid - Fetal development problems ### What does the result of the fetal echocardiogram show? - **Normal result (Reactive):** The heart rate of the fetus increases after its movements. This is a sign of good fetal health. - **Abnormal result (Non-Reactive):** Fetal heart rate does not increase in response to movement. In this case, the doctor may recommend additional tests such as BPP or CST ultrasound. ### Advantages of Fetal ECG - Examining the health of the fetus without risk - Prevention of childbirth problems - The mother's assurance of the health of the fetus - The possibility of early diagnosis of possible problems ### Is there a risk of fetal heart recording? No, NST is completely **safe** with no radiation or side effects. This test can be performed even in sensitive pregnancies. ### Conclusion ECG is a practical and safe tool to check the health of the fetus in the last weeks of pregnancy. If your doctor recommends this test, do it safely to be sure of the condition of your fetus. Timely diagnosis of any problem is an important step to maintain the health of mother and baby. ###
