The fetal heart is the developing heart of a fetus during pregnancy. It begins to form shortly after conception and is fully functional by around the sixth week of gestation. The heart plays a crucial role in circulating blood, providing oxygen and nutrients to the growing fetus through the placenta. Monitoring the fetal heart is an important part of prenatal care. Healthcare providers often use tools like a Doppler ultrasound or a fetal monitor to check the heart rate and rhythm. A normal fetal heart rate typically ranges from 120 to 160 beats per minute, indicating a healthy developing baby.
