A stress echocardiography, also called an echocardiography stress test or stress echo, is a procedure that determines how well your heart and blood vessels are working.
During a stress echocardiography, you’ll exercise on a treadmill or stationary bike while your doctor monitors your blood pressure and heart rhythm. When your heart rate reaches peak levels, your doctor will take ultrasound images of your heart to determine whether your heart muscles are getting enough blood and oxygen while you exercise.
As soon as your doctor tells you to stop exercising, they perform another ultrasound. This is to take more images
of your heart working under stress. You then have time to cool down. You can walk around slowly so that your heart rate can return to normal. Your doctor monitors your ECG, heart rate, and blood pressure until the levels return to normal.
