Fetal heart rate variability

Fetal heart rate variability refers to the natural changes in the time intervals between a baby's heartbeats during pregnancy. These fluctuations are a sign of a healthy, well-oxygenated fetus with a functioning nervous system. High variability indicates good fetal well-being, showing the baby's heart responds appropriately to its environment. Low variability may suggest stress, sleep, or potential issues needing further assessment. Monitoring this variability helps healthcare providers assess fetal health and detect possible problems early, ensuring timely intervention for the baby's safety.
