CTG (Cardiotocography)
Cardiotocography is an examination that simultaneously measures the fetal heart rate and uterine contractions.

For the examination to be successful, the fetal heart rate and uterine contractions must be recorded for at least 20 minutes.
During pregnancy, the examination is performed only when necessary, while during labor, it is conducted repeatedly.
Patients are referred for a CTG examination by a gynecologist.
