What is the normal range for fetal heart rate during the third trimester?

During the third trimester, the normal range for fetal heart rate is typically between 120 and 160 beats per minute. This range is indicative of a well-functioning fetal cardiovascular system and is an important marker for assessing fetal well-being.

A heart rate within this range helps ensure adequate oxygenation and nutrient delivery to the fetus. It is reflective of a healthy metabolic state and appropriate fetal response to stimuli, such as maternal activity or external stressors.

Heart rates below 120 beats per minute can indicate potential issues such as fetal distress or other complications. Conversely, heart rates significantly above 160 beats per minute may be a sign of fetal tachycardia, which could also signal underlying problems. Thus, the range of 120 to 160 beats per minute is widely accepted as the standard for monitoring fetal health during this crucial stage of pregnancy.
