CTG is designed to monitor the foetal heart rate and uterine contractile activity. It is performed from 34 weeks gestation.
What happens at CTG recording?
CTG is a test that involves two straps with sensors placed on the abdomen. One is an ultrasonic transducer used to measure the baby’s heartbeat. The other records uterine contractions. The sensors are connected to a monitor, which displays the results. The test usually takes about 30 minutes, but in the case of certain abnormalities it may be extended to one hour.
