Which fetal heart rate pattern during labor is usually associated with head compression and is typically benign?

• A. Late decelerations
• B. Accelerations
• C. Early decelerations
• D. Variable decelerations

Answer: (C)

Early decelerations reflect a vagal response to fetal head compression during contractions. As the head is squeezed, intracranial pressure rises and briefly slows the heart rate. The timing is aligned with the contraction—the decline begins with the contraction, reaches its lowest point at or near the peak, then returns to baseline as the contraction ends. This pattern usually indicates normal labor progression and is typically benign, requiring no intervention.

In contrast, late decelerations occur after the peak of contractions and can signal uteroplacental insufficiency, accelerations are reassuring increases in rate during activity, and variable decelerations are abrupt drops caused by cord compression and can be more concerning depending on timing and severity.
