What does it mean when fetal heart rate monitoring is irregular?
Disease description:
I am six months pregnant. Yesterday, during my prenatal checkup, the doctor performed fetal heart rate monitoring, and the fetal heart rate was consistently irregular—sometimes fast, sometimes slow. What could cause an irregular fetal heart rate tracing?

Under normal circumstances, the fetal heart rate ranges from 120 to 160 beats per minute and exhibits natural fluctuations—it does not remain fixed at a single value. If an abnormality is detected, it may indicate fetal hypoxia or congenital heart disease; therefore, prompt attention is required. Comprehensive diagnostic tests should be performed without delay, and any management or treatment must be carried out under the guidance of a physician.
We recommend that during pregnancy, you maintain good prenatal care, ensure a balanced and nutritious diet—including ample fresh fruits, vegetables, and protein-rich foods—and complete all recommended prenatal examinations on schedule. Regular antenatal check-ups are essential, and any abnormalities should be evaluated by a healthcare provider promptly.
