Cardiac Stress Test
The cardiac stress test is used to diagnose coronary heart disease by making it possible to see how the heart performs under pressure.
How does it work?
A cardiac stress test is performed by pushing the heart to work harder than usual. This stress can be induced by two different methods:
- Exercise. The patient is asked to perform exercise during the test, usually using a treadmill.
- Medication. The patient is given medication that accelerates the heart and simulates exercise.
During the stress test the patient has a set of electrodes attached to the chest. These electrodes are connected to a system that registers the activity and show the results in a monitor. Since the heart is beating faster and pumping more blood, the doctor can monitor for any anomalies that under normal working conditions, would not arise.
