A stress test evaluates how the heart performs under physical exertion, using a treadmill. It is essential for detecting coronary artery disease, assessing heart function after a heart attack, and determining exercise capacity. This test also monitors blood pressure response, detects arrhythmias, and evaluates oxygen saturation (O₂ levels) continuously throughout the assessment. A Stress Echocardiogram (Stress Echo) combines a stress test with ultrasound imaging to provide real- time visualization of heart function, helping identify areas of reduced blood flow and structural abnormalities.
