What is the primary purpose of an EKG stress test?

To measure blood pressure

To observe digestive function

To assess heart response to physical stress

The primary purpose of an EKG stress test is to assess how the heart responds to physical stress, which involves evaluating the heart's electrical activity during exercise or simulated physical exertion. During the test, patients typically walk on a treadmill or use a stationary bike, with EKG leads attached to monitor the heart's rhythm and activity. This process allows healthcare providers to identify abnormal heart rhythms, ischemic changes, or other cardiovascular issues that may occur when the heart is under increased demand.

This assessment is critical for diagnosing conditions such as coronary artery disease, determining safe levels of exercise for patients, and guiding treatment decisions based on the patient’s heart performance during stress. Understanding how a patient's heart responds during exertion is essential for providing appropriate cardiovascular care and management strategies.
