Intrapartum Abnormal Fetal HR Tracing - Causes of Bradycardia and Tachycardia - Differential Diagnosis Algorithm

Abnormal Variability:

 • Minimal/Absent Variability (< 5 bpm)

 • Marked Variability (> 25 bpm)

 • Sinusoidal Pattern Variability

 • Variability Absent Accelerations:

Decelerations:

 • Early decelerations

 • Variable decelerations

 • Late decelerations

 • Prolonged deceleration

Bradycardia

 • Fetal + Maternal

Tachycardia

 • Fetal + Maternal
