What is defined as fetal tachycardia?

Fetal tachycardia is characterized by a sustained increase in fetal heart rate. The correct definition establishes that a fetal heart rate greater than 160 beats per minute for 10 or more minutes indicates tachycardia. This threshold is significant because it marks the clinical designation used to identify potential fetal distress or pathophysiological conditions that may require further assessment or intervention.

Understanding this concept is crucial in neonatal care since prolonged tachycardia can indicate issues such as maternal fever, infection, or fetal hypoxia. Monitoring fetal heart rate patterns is essential for evaluating fetal well-being during labor and delivery. By recognizing tachycardia, healthcare providers can make timely decisions to optimize the outcomes for both the mother and the infant.
