What is the typical normal fetal heart rate range detected during late first trimester?

The typical normal fetal heart rate range during the late first trimester is between 120 and 160 beats per minute (bpm). At this stage of pregnancy, the fetus's heart rate reflects its developing cardiovascular system and is indicative of healthy fetal growth and metabolic activity. A heart rate within this range is associated with a well-functioning fetal condition and is used by healthcare providers as a standard reference when monitoring fetal health. Rates lower than 120 bpm or higher than 160 bpm can be concerning and may warrant further investigation to rule out any potential complications or issues with fetal well-being. Monitoring and interpreting fetal heart rate are essential in prenatal care, as deviations from the normal range can be signals of distress or other medical concerns.
