A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting.

The Bruce treadmill test estimates maximum oxygen uptake using a formula and the performance of the subject on a treadmill as the workload is increased. The test is easy to perform in a medical office setting, does not require extensive training or expensive equipment, and it has been validated as a strong predictor of clinical outcomes. [4]
A person might not be aware that they are the victim of hypothermia. ... even more demanding on the heart than taking a treadmill stress test, according to research we’ve conducted ...

The Harvard step test, in scientific literature sometimes referred to as the Brouha Test, is a type of cardiac stress test for detecting and diagnosing cardiovascular disease. It is also a good measurement of fitness and a person's ability to recover after a strenuous exercise by checking the recovery rate.
