GXT (Graded Exercise Test)

A Graded Exercise Test (GXT) is a diagnostic procedure where a person walks or pedals on a treadmill or bike, with the intensity gradually increasing. This test monitors how the heart responds to physical stress in real-time by measuring factors like heart rate, blood pressure, and oxygen use. It helps doctors assess cardiovascular health, detect issues like coronary artery disease, and determine safe exercise levels. The test is carefully controlled and tailored to each individual, providing valuable information about overall fitness and heart function under stress.
