The lead is then plugged into the monitor and a typical CTG reading is printed on To appropriately interpret a fetal monitoring tracing, the systematic approach below Uterine contraction patterns can provide information about the progress of labor.

The pregnancy stress test, as it's called by many mothers, is a test that goes by many other names, including the oxytocin challenge test (OCT). It was later renamed as the contraction stress test (CST). This is one of the many potential tests that can be done to check on the health and well-being of your baby in pregnancy.
