What is the normal fetal heart rate range?

Understanding normal fetal heart rate is about the baseline speed of the beating heart in a healthy fetus during mid to late pregnancy. The typical baseline falls around 110–160 beats per minute, with the average often near 140–150 bpm. Values outside this range raise concern: rates above ~160–170 bpm suggest tachycardia, which can be associated with fetal distress, infection, or maternal factors; rates below ~110 bpm suggest bradycardia, which can indicate conduction problems, cord compression, or hypoxia. The other options fall into bradycardia or tachycardia ranges that are not considered normal baselines, so the 110–160 bpm window is the standard reference for a normal fetal heart rate.
