Reactive nonstress test performed 8 days before the patient's estimated delivery date

Reactive nonstress test. The baseline fetal heart rate is between 130 and 140 beats per minute. There are two accelerations >15 beats per minute; one peaks at approximately 170 beats per minute and the other peaks at approximately 160 beats per minute. The duration of each acceleration exceeds 20 seconds. Variability is moderate (6 to 25 beats per minute).
The top tracing is the fetal heart rate. The y-axis reflects the fetal heart rate measured in beats per minute. The x-axis reflects time; each of the smallest divisions represents 10 seconds with one minute between bold vertical lines.
The bottom tracing shows the frequency and duration of uterine contractions.
