What is an echocardiogram?
An echocardiogram (an echo) is a noninvasive diagnostic test that can offer valuable information about the structure and function of your heart, including the sizes of different chambers, its ability to pump blood and the competency of your heart valves.
Also referred to as a diagnostic cardiac ultrasound, this test uses high-frequency sound waves and special computer technology that allows your doctor to take pictures of your heart’s structure, including its size, shape and movements.
Why would I need an echocardiogram?
Providers use echocardiography to investigate symptoms and identify many heart and vascular conditions, including:
- Atherosclerosis
- Aortic aneurysm
- Angina (chest pain)
- Arrhythmia
- Cardiomyopathy
- Congenital heart disease
- Congestive heart failure
- Coronary artery disease
- Heart attack
- Heart valve disease, such as aortic stenosis and mitral valve regurgitation
- Pericarditis
- Pericardial effusion
- Stroke
How is an echocardiogram done?
There are a few different types of echocardiograms, but they all use sound waves to produce images. During the test, an ultrasound wand or probe sends sound waves to your heart that “echo” back to a computer monitor. The monitor uses those sound waves to create pictures of the heart and valves.
Some echo tests use Doppler technology to show the direction and speed of blood flow and help doctors identify problems with your heart valves.
How long does an echocardiogram take?
An echocardiogram usually takes 30 to 60 minutes. It may take longer if other imaging tests are required.
Types of echocardiograms
Depending on your symptoms and other factors, your provider may recommend one of several types of echocardiograms.
What to expect during an echocardiogram
Echocardiogram results
After the test, the sonographer will send the results to your referring physician, who will review the results. Your physician may want to schedule a follow-up visit to discuss them.
If an echo test confirms a diagnosis, your treatment options will depend on the specific condition and the severity of your symptoms. In other cases, an echo test might not be enough to make an accurate diagnosis. Your doctor may recommend other tests to diagnose your condition, such as electrophysiology, a procedure called coronary catheterization or specialized imaging, such as CT or MRI scans.
