During this test, you will be connected to a heart monitor while walking on a treadmill. Information about your heart function is gathered through measurement of your heart rate, breathing, blood pressure and heart rhythm findings, as well as how tired you become when exercising. This test can help diagnose coronary artery disease, provide information about symptoms such as chest pain, and determine a safe level of exercise. An exercise perfusion stress test is similar to an exercise stress test, except a perfusion test measures blood flow to your heart using small amounts of radioactive tracers. These tracers are safe and help provide an image of the blood flow to your heart during exercise walking on a treadmill or pedaling on a stationary bicycle and while at rest.
How to Interpret Your Stress Test Results
Cardiac exercise stress testing: What it can and cannot tell you - Harvard Health
A cardiac stress test also referred to as a cardiac diagnostic test , cardiopulmonary exercise test , or abbreviated CPX test is a cardiological test that measures the heart 's ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by intravenous pharmacological stimulation. Cardiac stress tests compare the coronary circulation while the patient is at rest with the same patient's circulation during maximum cardiac exertion, showing any abnormal blood flow to the myocardium heart muscle tissue. The results can be interpreted as a reflection on the general physical condition of the test patient.
Cardiac stress tests look at how your heart reacts to the stress of an increased workload. There are several types of cardiac stress tests. But basically, the stress can come from two different stimuli—exercise or medicines.
There are various types of cardiac stress tests which are used to diagnose many serious heart conditions. There are in all four types of tests which involve the use of radioactive tracers. These tests can also help the doctors to decide the course of treatment and to determine whether it is better to continue with treatment or perform a surgery. The Thallium Stress Test is one such test in which thallium is used to show the flow of the blood through the vessels, into the heart. This stress test is useful because it can help monitor stress levels for patients who have had a heart attack.
