A stress echocardiogram, commonly known as stress-echo, is a diagnostic procedure that combines ultrasound imaging of the heart with physical stress to assess heart function and blood flow. During the test, patients undergo echocardiography while at rest and then again after physical exertion induced either by exercise or medication. This allows healthcare providers to evaluate how the heart responds to stress, aiding in the diagnosis of coronary artery disease, heart valve disorders, and other cardiac conditions. The test is non-invasive and helps guide treatment decisions by providing valuable information about the heart's performance under different conditions.
