Assessing fetal heart function is crucial for monitoring the health and development of the fetus during pregnancy. This assessment can be performed using various methods, including:
Ultrasound (Sonography):
- Doppler Ultrasound: Measures blood flow and heart rate. It can detect issues like abnormal heart rhythms or congenital heart defects.
- Fetal Echocardiography: A detailed ultrasound specifically focused on the fetal heart to evaluate its structure and function.
Non-Stress Test (NST):
- Monitors the fetal heart rate and its variability in response to fetal movements. A healthy fetus typically shows an increase in heart rate with movements.
Biophysical Profile (BPP):
- Combines NST with ultrasound to assess fetal heart rate, muscle tone, movement, breathing, and amniotic fluid volume. Each component is scored to evaluate overall fetal well-being.
Cardiotocography (CTG):
- Continuous recording of fetal heart rate and uterine contractions. It helps detect patterns that may indicate fetal distress.
Magnetic Resonance Imaging (MRI):
- In rare cases, fetal MRI can provide additional information about the fetal heart and surrounding structures when ultrasound results are inconclusive.
Parameters Assessed in Fetal Heart Function
- Heart Rate: Normal fetal heart rate ranges from 110 to 160 beats per minute. Abnormalities can indicate issues like fetal distress (bradycardia or tachycardia).
- Heart Rhythm: Regular rhythm indicates a healthy heart function, while irregular rhythms may suggest arrhythmias.
- Blood Flow: Evaluated using Doppler ultrasound to ensure there is proper circulation to and from the fetal heart.
- Heart Anatomy: Detailed structure and function assessment to rule out congenital heart defects.
Indications for Fetal Heart Function Assessment
- Maternal conditions (e.g., diabetes, hypertension).
- Abnormal findings in routine prenatal care.
- History of congenital heart disease in the family.
- Decreased fetal movements.
- Multiple pregnancies.
Follow-Up and Intervention
If abnormalities are detected, further testing and close monitoring will be necessary. In some cases, early delivery or interventions after birth may be required to manage identified issues.
