A cardiac stress test evaluates how your heart performs during physical activity. During the test, you will walk on a treadmill while your heart rhythm, blood pressure, and symptoms are monitored.
A stress echocardiogram combines a treadmill stress test with ultrasound images of the heart taken before and immediately after exercise.
These tests help your doctor assess blood flow to the heart, heart function during exercise, and possible coronary artery disease.
Why Is Definity Contrast Used?
At our clinic, Definity contrast is used in most stress echocardiograms to improve image quality. Administered through an IV by the technologist, this ultrasound-enhancing agent provides clearer views of the heart’s chambers and helps assess its pumping function.
Preparation Guide
Please review this checklist before coming to your appointment.
Light Fasting
Do not eat for 2 to 3 hours before your test. Water is allowed.
Exercise-Ready Clothing
Wear comfortable loose-fitting clothing and walking or running shoes suitable for treadmill exercise.
No Lotions or Oils
Do not apply lotions or oils on your chest so electrodes can attach properly.
Bring Your Documents
Bring a list of your medications, your requisition form, and your health card.
What to Expect
During the Exam
Electrodes will be placed on your chest. You will walk on a treadmill while speed and incline gradually increase. Blood pressure and heart rhythm are monitored throughout. For stress echocardiography, ultrasound images are taken before and immediately after exercise. The test usually takes 30 to 45 minutes.
When the Test May Be Stopped
The test may be stopped if you develop significant symptoms, your heart rhythm changes, or you reach your target heart rate. Your care team will closely monitor you throughout.
If you are experiencing symptoms such as fever, chest pain at rest, or a recent illness, please contact our clinic before your appointment. You may resume normal activities after the test unless your physician advises otherwise.
