A stress test is designed to evaluate the heart's ability to pump blood effectively while under physical stress, typically induced by exercise or medication. During the test, the heart is placed under conditions that mimic exercise, which is necessary to uncover any potential issues that may not be visible when the body is at rest. This assessment is crucial as it helps physicians determine how well the heart functions during increased activity levels and can indicate the overall health of the cardiovascular system.

By evaluating the heart under stress, the test can reveal problems such as insufficient blood flow or oxygen supply to the heart muscle, which might not show up during routine examinations. Understanding the heart's performance under these conditions aids in diagnosing conditions like coronary artery disease, arrhythmias, and other cardiac issues.

The other options focus on different aspects of heart function. Measuring the strength of heartbeats pertains more to muscular capability, while assessing electrical activity and identifying rhythms typically relate to rest rather than stress conditions. Thus, they don't capture the essence of what a stress test aims to evaluate.
