The CST is one of the first forms of fetal surveillance; it is still the only form that tries to use the principle of induced stress to reveal marginal placental insufficiency. With the expansion of biophysical evaluation, there are many choices in antenatal testing. Clearly the CST should not be the only form of testing to follow high-risk pregnancies. However, its proved efficacy and close correlation with intrapartum monitoring make it an essential tool. With nipple stimulation techniques, it is an easy and quick method for evaluating the fetus. Clinicians who follow high-risk pregnancies need to understand fully the administration and proper interpretation of the CST.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
