Exercise Stress Test
An Exercise Stress Test (sometimes called a treadmill test or cardiac stress test) checks how your heart works during exercise. It helps doctors find problems such as coronary artery disease and other heart conditions. The test shows how your heart responds when it has to work harder.
What happens during an Exercise Stress Test?
- Electrodes applied: Small sticky pads (like in a standard ECG) are placed on your chest to record your heart’s electrical activity.
- Walking on a treadmill: You walk on a treadmill for 6–10 minutes while your heart is monitored.
- Blood pressure checks: Your blood pressure is measured at intervals during the test.
- Monitoring: The ECG and blood pressure readings together show how your heart responds to exercise.
The whole appointment takes about 30 minutes.
