What Does GXT Stand For?

GXT stands for Graded Exercise Tolerance Stress Test

The Graded Exercise Tolerance Stress Test (GXT) is a diagnostic assessment used to evaluate an individual's cardiovascular response to physical exercise. During the test, the subject performs progressively intense exercise, typically on a treadmill or stationary bike, while vital parameters such as heart rate, blood pressure, and electrocardiogram (ECG) are closely monitored. The GXT helps physicians assess cardiovascular fitness, diagnose potential heart-related issues, and evaluate the effectiveness of treatments or exercise regimens. It is commonly used in cardiology and sports medicine to determine an individual’s exercise capacity and identify any exercise-induced abnormalities.
