Define tachycardia in the context of fetal heart rate.

Tachycardia, in the context of fetal heart rate, is defined as a heart rate that exceeds 160 beats per minute. This condition indicates that the fetal heart is beating at an unusually high rate, which can be a sign of various underlying issues, such as maternal fever, infection, or fetal distress. Monitoring fetal heart rates is crucial during labor and delivery, as deviations from normal ranges can prompt further assessment and interventions to ensure the well-being of both the mother and the fetus. Understanding this definition helps healthcare professionals assess fetal condition accurately and respond appropriately to any complications that may arise during labor.
