What does the term "tachycardia" indicate in a fetal heart rate assessment?

The term "tachycardia" in a fetal heart rate assessment refers to a heart rate that exceeds 160 beats per minute (bpm). In this context, it is critical to understand that fetal heart rates typically range between 110 and 160 bpm, which is considered normal. A rate above 160 bpm indicates potential stress on the fetus, which could result from various factors such as maternal fever, dehydration, or fetal hypoxia. Identifying tachycardia early during fetal monitoring is essential, as it can guide clinical decision-making and prompt timely interventions if necessary. This understanding underlines the significance of monitoring fetal heart rate patterns to assess fetal well-being effectively.
