WHAT IS A STRESS ECHOCARDIOGRAM?
This test involves comparing images of the contraction of your heart at rest and following exercise.
Commonly referred to as a ‘stress echo’, this test involves an echocardiogram taken before and after an exercise stress test. The echo produces images of the heart valves and chambers so that your doctor can see how your heart is functioning and if there is evidence of heart muscle weakness during exercise. This may indicate severe coronary artery disease. Exercise testing measures the performance and capacity of your heart and blood vessels, to determine whether your heart receives enough oxygen and proper blood flow when you are under stress (e.g., exercising). There are instances where people are unable to exercise to increase their heart rate. A pharmacological stress test called a Dobutamine Stress test is available. Medication is given via a vein to increase the heart rate without the need to exercise.
WHY DO I NEED TO HAVE A STRESS ECHOCARDIOGRAM?
Your doctor will request a stress echo to evaluate you for coronary artery and valve disease.
