An exercise test is a treadmill test to assess cardiac status.
During an exercise test an electrocardiogram is performed whilst the patient is walking on a treadmill. Blood pressure, heart rate and oxygen levels are also monitored.
This is commonly used to diagnose coronary artery disease although more sophisticated non-invasive tests are often now used for this role, for example stress echocardiography, cardiac CT or cardiac MRI.
Exercise tests can also be used in the assessment of heart valve disease or heart muscle disease (cardiomyopathy).
