Which fetal heart rate indicates a concerning finding that requires follow-up?

A fetal heart rate of 180 beats per minute is considered a concerning finding that requires follow-up. The normal range for fetal heart rate typically falls between 110 to 160 beats per minute. When the heart rate exceeds 160 beats per minute, this is termed tachycardia, which can indicate various conditions that may need further investigation, such as maternal fever, fetal hypoxia, or other stress factors affecting the fetus. Monitoring and potentially assessing the underlying causes or interventions might be necessary to ensure the well-being of the fetus.

Conversely, heart rates of 120, 160, and 140 beats per minute fall within the normal range or at the upper limit of normal, signaling no immediate concerns that would necessitate further follow-up.
