hyperstimulation - induction of labour

Last edited 11/2021 and last reviewed 11/2021

  • is overactivity of the uterus as a result of induction of labour

  • is variously defined as uterine tachysystole (more than 5 contractions per 10 minutes for at least 20 minutes) and uterine hypersystole/hypertonicity (a contraction lasting at least 2 minutes)

  • may or may not be associated with changes in the fetal heart rate pattern (persistent decelerations, tachycardia or increased/decreased short term variability)
