Echocardiography (Echo)

An echocardiogram (echo) is an imaging test. It helps your doctor evaluate your heart. This test:

• Is safe and painless.
• Can be done in a hospital, test center, or doctor’s office.
• Bounces harmless sound waves (ultrasound) off the heart. A transducer (device that looks like a microphone) is used.
• Helps show the size of your heart. It also helps show the health of the heart’s chambers and valves.

Before Your Echo

• Discuss any questions or concerns you have with your doctor.
• Mention any over-the-counter or prescription medications, herbs, or supplements you’re taking.
• Allow extra time for checking in.
• Wear a two-piece outfit for the test. You may be asked to remove clothing and jewelry from the waist up. If so, you’ll be given a short hospital gown.

During Your Echo

• Most echo tests take 10-20 minutes.
• Small pads (electrodes) are placed on your chest to monitor your heartbeat.
• A transducer coated with cool gel is moved firmly over your chest. This device creates the sound waves that make images of your heart.
• At times, you may be asked to exhale and hold your breath for a few seconds. Air in your lungs can affect the images.
• The transducer may also be used to do a Doppler study. This test measures the direction and speed of blood flowing through the heart. During the test, you may hear a “whooshing” sound. This is the sound of blood flowing through the heart.
• The images of your heart are stored on a computer or recorded on video. This is so your doctor can review them later.

After Your Echo

• Return to normal activity unless your healthcare provider tells you otherwise.
• Be sure to keep follow-up appointments.

Your Test Results

Your doctor will discuss your test results with you during a future office visit. The test results help the doctor plan your treatment and any other tests that are needed.
