There are different types of echocardiograms such as:
- Contrast echocardiogram—A special dye is used to highlight some areas.
- Stress echocardiogram—Done while the heart's workload is increased.
- Echocardiogram with Doppler ultrasound—Tracks flow of blood through the heart.
- Transesophageal echocardiogram——Tools are placed down the throat to get better images.
Reasons for Test
An echocardiogram may be used to:
- Look for injury or illness of heart, heart valves, or sac around the heart
- Check how well the heart is working
- Find and define birth defects or abnormal growths
- Follow treatment or disease progress
There are no major problems with this test. Types of echocardiogram, like stress, may have specific risk.
What to Expect
Prior to Test
Your doctor may review previous tests. It will help decide what type of test is best.
Description of Test
This is a process for a basic echocardiogram. A gel is put on your chest. A small, hand-held device is pressed and moved against your skin. You will not feel anything except the device on your skin. Images of the heart will appear on a screen in the room. The doctor may move the device around. It will help to get a better view of different areas. You may be asked to change positions, and slowly breathe in or out, or hold your breath.
The gel is wiped from your chest. If you are well, you can go home.
How Long Will It Take?
30 to 60 minutes
Will It Hurt?
Your doctor will talk to you about the results.
