Echocardiogram

What is an echocardiogram?

An echocardiogram—often called an echo—is an ultrasound examination of the heart. A handheld device called a transducer sends and receives sound waves, which are converted into moving images on a monitor.

Unlike an X-ray, a standard echocardiogram does not use ionizing radiation. It is performed from outside the body and is commonly used to collect information about heart structure and function.

What the images can show

An echocardiogram can provide information about:

• The size and shape of the heart’s chambers
• The movement and pumping action of the heart muscle
• The structure and movement of the heart valves
• The direction and speed of blood flow in selected areas
• Fluid around the heart or other structural findings

The reason for your test determines which measurements and views are required.

What to expect during the test

You may be asked to change into a gown so the technologist can access areas of your chest. You will usually lie on an examination table, sometimes turned slightly onto your left side.

The technologist places ultrasound gel on the skin and moves the transducer across several positions on the chest. You may be asked to change position, hold your breath briefly, or breathe in a particular way so specific views can be recorded. Some pressure from the transducer may be needed to obtain a clear image; tell the technologist if you are uncomfortable.

Preparing for your appointment

Preparation for a standard chest echocardiogram is often straightforward. Follow the clinic’s instructions and wear clothing that is easy to change. Continue medications as directed unless an appropriate healthcare professional has given you different instructions.

There are several types of echocardiograms, and some require different preparation. Check your appointment information rather than assuming instructions for one type apply to another.

After the echocardiogram

The gel is removed and you can usually return to your usual activities unless you were told otherwise. The images and measurements must be reviewed before a report is completed.

The technologist collecting the images may not be able to discuss the result. Ask the clinic or your referring healthcare provider who will review the report with you and how follow-up will be arranged.
