EXAMS PERFORMED IN THE ECHOCARDIOGRAPHY (ECHO) LAB
Echocardiogram (Echo)
An echocardiogram, also called an echo, is a safe and painless test that uses high-
frequency sound waves (ultrasound) to create images of the heart. A medical professional
known as a cardiac sonographer uses a small, handheld device called a transducer to
create images of the heart’s function, heart valves, and other surrounding structures. Using
sound wave technology, blood flow through the heart also can be evaluated.
Why is an echocardiogram performed?
The test is used to evaluate:
• Overall heart function.
• Various types of heart disease, including valve, myocardial, and pericardial diseases
as well as infective endocarditis, cardiac masses, and congenital heart disease (heart
problems present at birth).
• How heart disease progresses over time.
• How well medical or surgical treatments worked.
Can I eat or drink on the day of the test?
Yes. Eat and drink as you normally would on the day of the test.
Should I take my medications on the day of the test?

What should I wear on the day of the test?

test.
