echo test

Depending on what information your doctor needs, you may have one of several types of echocardiograms.

A cardiac sonographer will place three electrodes (small, flat, sticky patches) on your chest. This site complies with the HONcode standard for trustworthy health information: verify here.

Serious complications from stress tests are very uncommon. Echo can show how well your heart is pumping blood.
Don’t eat or drink until the sedative wears off, which takes an hour after the test.

Your doctor may tell you to stop taking certain heart medications on the day of your test.

Your test will take place in the Echo Lab located at J1-5. This allows your doctor to look at the anatomy of your heart from many different angles and to watch your heart rhythm. You may or may not hear the sounds during the test. These echoes are picked up by the probe and turned into a moving image on a monitor while the scan is carried out.

A computer converts the echoes into moving images on a monitor.

See our safety precautions in response to COVID-19. A three-dimensional (3D) echocardiogram creates detailed 3D images of the heart. Next review due: 23 July 2021, problems with the heart valves – problems affecting the valves that control the flow of blood within the heart, a transoesophageal echocardiogram (TOE) – where a small probe is passed down the throat into your gullet and stomach (your throat will be numbed with, a stress echocardiogram – an echocardiogram carried out during or just after a period of exercise on a treadmill or exercise bike, or after being given an injection of a medication that makes your heart work harder, a contrast echocardiogram – where a harmless substance called a contrast agent is injected into your bloodstream before an echocardiogram is carried out; this substance shows up clearly on the scan and can help create a better image of your heart. The use of local anesthetics, sedatives, and contrast dyes during the exam may trigger an allergic reaction in some people.

There are also several other types of echocardiogram that can be carried out: The type of echocardiogram you will have depends on the heart condition being assessed and how detailed the images need to be.

For instance: If a doctor ordered a transthoracic echocardiogram, the sonographer will apply a gel to the chest. Often, your doctor will tell you to take only half of your usual morning dose and to eat a light meal 4 hours before the test. Don’t drink or eat anything with caffeine (such as cola, chocolate, coffee, tea, or medications) for 24 hours before.

Echo also can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack. It shows how well your heart tolerates activity. Doppler ultrasound often is used during echo tests.

Your heart will begin beating faster and stronger. A transesophageal electrocardiogram may trigger a person’s gag reflex when the sonographer guides the tube down the throat.

You will need to arrange transportation home since you may feel groggy from the sedative. This allows the sonographer to get better pictures of your heart. Vital signs will be monitored for about 20-30 minutes. All types of echocardiogram use high frequency sound waves. They can wear a hospital gown if they wish to cover themselves during the exam. Your doctor will tell you more about which is best for you.

A sonographer will take a transthoracic echocardiogram before and after the exercise.

For people who get a transesophageal echocardiogram, a doctor will recommend avoiding eating or drinking anything for at least 4 hours before the exam. In the meantime, they’ll watch the EKG monitor for changes and ask about any symptoms. The pictures of your heart are then recorded as your doctor moves the transducer around in your esophagus and stomach. During the test, the doctor will monitor heart rate, blood pressure, and the heart’s electrical activity. These tests are safe for adults, children, and infants. Once the sedative takes effect, a doctor will guide a small transducer on the end of a long tube down the throat and esophagus until it reaches the back of the heart.

This is a relatively safe procedure.

You'll lie on your back or left side on an exam table or stretcher. The medical team will slowly raise the intensity. Blood that flows toward the transducer appears red, while blood that flows away looks blue.

An echocardiogram can help diagnose and monitor certain heart conditions by checking the structure of the heart and surrounding blood vessels, analysing how blood flows through them and assessing the pumping chambers of the heart. Echo also can help your doctor find the cause of abnormal heart sounds, such as heart murmurs. The National Heart, Lung, and Blood Institute (NHLBI) leads or sponsors many studies aimed at preventing, diagnosing, and treating heart, lung, blood, and sleep disorders.
You'll be asked to lie on your left side and the probe will be moved across your chest. The test takes about 30 minutes to perform.

This test usually requires that you don't eat or drink for 8 hours prior to the test. There are several different ways an echocardiogram can be carried out, but most people will have a transthoracic echocardiogram (TTE). Sound waves are emitted during the test, which bounce off your heart and create a moving image of it on a screen. The probe is attached by a cable to a nearby machine that will display and record the images produced.

Do not stop taking any medication without first talking with your doctor. There will be a small amount of gel on the end to help create clearer pictures. (See above for more information about how transthoracic echo and TEE are done.). For example, a stress echocardiogram may be recommended if your heart problem is triggered by physical activity, while the more detailed images produced by a TOE may be more useful in helping plan heart surgery. The technician will perform a resting EKG, measure your resting heart rate, and take your blood pressure. An echocardiogram (often called an "echo") is a graphic outline of your heart's movement. When recommended, the test is commonly done at about 18 to 22 weeks of pregnancy.

The human ear can't hear ultrasound waves. Your doctor may recommend echocardiography (echo) if you have signs or symptoms of heart problems. If you're having a stress echo, you may need to take steps to prepare for the stress test.

Transesophageal: A device called a transducer is inserted down your throat into your esophagus (the swallowing tube that connects your mouth to your stomach.) This study is located in Philadelphia, Pennsylvania. The medicine will be injected into one of your veins.

The transducer records the sound wave echoes from your heart. A doctor will order an echocardiogram if they suspect that someone has heart problems. There are several types of echocardiography (echo)—all use sound waves to create moving pictures of your heart.

You'll undress from the waist up and lie on an examination table or bed.

Doctors can use a fetal echocardiogram to view an unborn baby’s heart. If you own a glucose monitor, bring it with you to check your blood sugar levels before and after your test. This allows your doctor to get more detailed pictures of your heart.

An echocardiogram can help your doctor diagnose several kinds of heart problems, including: Cleveland Clinic Heart and Vascular Institute. The process described above is similar to the process for fetal echo. Whenever a person receives sedatives, there is a chance that the stomach contents may enter the lungs. You should let the sonographer know if you feel too uncomfortable. The results of a doppler ultrasound can reveal problems with valves or holes in the walls of the heart and assess how the blood is traveling through it. This test involves placing an ultrasound wand called a transducer on the outside of the chest, near the heart.

A three-dimensional (3D) echo creates 3D images of your heart.

You usually can go back to your normal activities right after having echocardiography (echo). The pictures show the size and shape of your heart. You might hear them call it “echo” for short. The electrodes are attached to an EKG that charts your heart's electrical activity during the test. If you have a transesophageal echocardiogram, you may be watched for a few hours at the doctor's office or hospital after the test.

Your doctor may order an echocardiogram to: There are several types of these tests. Echo is often combined with tests called Doppler ultrasound and color Doppler to check the blood flow through the heart's valves. However, there are some risks associated with the less common types of echocardiogram.

Your blood pressure, the oxygen content of your blood, and other vital signs will be checked during the test.

The appointment will take about 60 minutes. Echocardiography uses ultrasound waves to create a picture of the heart, called an echocardiogram (echo).

The testing area is supervised by a physician. Echo can detect possible blood clots inside the heart, fluid buildup in the pericardium (the sac around the heart), and problems with the aorta. Page last reviewed: 23 July 2018 This type of echo involves placing a device called a transducer on your chest. A doctor might order a transesophageal echocardiogram if they want more detailed or clearer images of the heart than those that a transthoracic echocardiogram can produce.

During this test, your doctor threads the transducer into your heart blood vessels through a catheter in your groin. National Heart, Lung, and Blood Institute: “Echocardiography.”, Cleveland Clinic: “Exercise Stress Echocardiogram,” “Intravascular Ultrasound.”. The test takes about 10 to 30 minutes. Echocardiography (echo) is painless; the test usually takes less than an hour to do.

If you take pills to control your blood sugar, do not take your medication until after the test is complete unless otherwise directed by your doctor. You’ll lie flat with your leg straight for 3 to 6 hours.

You should feel no major discomfort during the test.

Don’t eat or drink anything for 6 hours before the test. Doctors may use 3D echo to diagnose heart problems in children. Philadelphia, Pa.: Saunders Elsevier; 2019. https://www.clinicalkey.com. For a pharmacological stress test, you'll be given medicine to increase your heart rate.

Be sure to arrange for a ride home. There's also a small chance of the probe damaging your throat.
