Definition: This test is also known as a stress test or exercise tolerance test (ETT) or treadmill test.
This is a variation on an ECG which records the activity of the heart as it works harder by walking on a treadmill. The exercise ECG records changes that the heart experiences due to an insufficient blood supply. It can be used to diagnose angina and assess severity, as well as ruling out cardiac causes for patient’s symptoms.
The following video from British Heart Foundation demonstrates a patient guide to an ETT.
