What term describes decelerations that occur as an isolated event not linked to uterine contractions?

• A. Episodic decelerations
• B. Periodic decelerations
• C. Repetitive decelerations
• D. Transient decelerations

Answer: (A)

Episodic decelerations are defined as decelerations in fetal heart rate that occur sporadically and are not associated with uterine contractions. This term highlights the nature of these decelerations, which can occur at any time during fetal monitoring, independent of the uterine activity. This distinction is crucial in fetal heart monitoring, as it helps healthcare providers assess the well-being of the fetus and identify any potential issues that may need to be addressed. In contrast, periodic decelerations are those that are directly linked to contractions, typically occurring with each contraction and reflecting changes in uteroplacental blood flow. Repetitive decelerations imply that these events happen consistently during a specific timeframe, often associated with contractions. Transient decelerations may imply short fluctuations in heart rate that do not indicate a recurring pattern. Thus, episodic decelerations are specifically characterized by their lack of correlation with uterine activity, making this the correct choice for the question posed.
