Table 1 FIGO guidelines for interpretation of fetal heart rate via continuous cardiotocography.
From: Proposing a machine learning-based model for predicting nonreassuring fetal heart
Fetal heart pattern designation | Description |
|---|---|
Reassuring | Baseline heart rate: 110–160 bpm Variability: 5–25 bpm Decelerations: No repetitive decelerations |
Nonreassuring | Baseline heart rate: Less than 100 bpm Variability: Reduced variability for > 15 min Increased variability for > 30 min or Sinusoidal pattern for > 30 min Decelerations: Repetitive late or prolonged decelerations during > 30 min–20 min if reduced variability or One prolonged deceleration with > 5 min |
