What does tachysystole refer to in terms of contraction frequency?

Tachysystole is defined as an increased frequency of contractions that can signify hyperactivity of the uterus during labor. Specifically, it refers to having more than five contractions within a 10-minute window, averaged over a 30-minute period. This condition can lead to reduced uteroplacental blood flow and may compromise fetal oxygenation, requiring careful monitoring and management during labor.

Understanding of contraction frequency is essential in fetal monitoring, and recognizing tachysystole is critical for ensuring the health and safety of both the mother and the fetus. Options indicating low, normal, or variable contraction frequencies do not meet the definition or implications of tachysystole, as they do not reflect the pathological increase in contractions that can affect fetal wellbeing.
