Your doctor monitors your ECG, heart rate, and blood pressure until the levels return to normal.Conventional and density-fitting mp2 test of mp2 itself and setting scs-mp2 You can walk around slowly so that your heart rate can return to normal. This is to take more images of your heart working under stress. Stress echocardiographyĪs soon as your doctor tells you to stop exercising, they perform another ultrasound. Tell your doctor right away if you feel dizzy or weak, or if you have chest pain or pain on your left side. You’ll probably need to exercise for 6 to 10 minutes, or until you feel tired, to raise your heart rate as much as possible. Depending on your physical condition, your doctor may ask you to increase the intensity of your exercise. Stress testĪfter the resting echocardiogram, your doctor next has you exercise on a treadmill or stationary bicycle. This device emits sound waves to create images of your heart’s movement and internal structures. They’ll apply a special gel to your skin and then use a device called a transducer. Next, you’ll lie on your side, and your doctor will do a resting echocardiogram, or ultrasound, of your heart. You’ll likely have your blood pressure taken throughout the test as well. The ECG measures your heart’s electrical activity, especially the rate and regularity of your heartbeats. The electrodes connect to an electrocardiograph (ECG). Your doctor begins by placing 10 small, sticky patches called electrodes on your chest. Your doctor needs to see how your heart functions while you’re at rest to get an accurate idea of how it’s working. What happens during a stress echocardiography? Resting echocardiography Because you will exercise, make sure to wear good walking or running shoes. Wear comfortable, loose-fitting clothes. Let your doctor know if you take medication to control diabetes as well. You shouldn’t take certain heart medications, such as beta-blockers, isosorbide-dinitrate, isosorbide-mononitrate (Isordil Titradose), and nitroglycerin, before the test. If you take medications, ask your doctor whether you should take them on the day of the test.Don’t drink coffee or take any medications that contain caffeine without checking with your doctor.Don’t smoke on the day of the test because nicotine can interfere with your heart rate.Make sure not to eat or drink anything for three to four hours before the test.It normally takes between 45 and 60 minutes.īefore you take the test, you should do the following: This test usually occurs in an echocardiography laboratory, or echo lab, but it can also occur in your doctor’s office or other medical setting. How do I prepare for a stress echocardiography?
