Which heart rate indicates tachycardia in a fetus?

Tachycardia in a fetus is typically classified as a heart rate greater than 160 beats per minute (bpm). When evaluating fetal heart rates, understanding the normal ranges is critical. The normal fetal heart rate range is generally considered to be between 110 and 160 bpm.

When the heart rate exceeds 160 bpm, it indicates that the fetus is experiencing tachycardia. This condition can be caused by various factors, including maternal fever, uterine contractions, medications, or fetal distress. Recognizing tachycardia is essential for monitoring fetal well-being, as it may suggest underlying issues that could necessitate further evaluation or intervention.

The other choices reflect heart rates that fall within normal limits or are considered bradycardia, which is typically defined as a heart rate below 110 bpm. Understanding these classifications is vital for managing fetal health during pregnancy and labor.
