THE MEDICAL IMAGING EXPERIENCE
INFORMATION FOR THE PATIENT
ECHOCARDIOGRAM

WHAT IS IT?
Ultrasound procedures involve the use of very high frequency sound waves. The actual sound cannot be heard with the human ear. The sound waves are sent into the body using a hand held instrument called a transducer. The various structures in the body including organs, tissue and fluids (such as blood and water) reflect sound waves differently because of their different density. Some of the sound waves reflect back to the transducer much like your voice echoes back to you in an empty building. The reflected sound waves are received by the transducer and sent to a computer to be processed into pictures.

WHAT WILL HAPPEN TO ME?
The sonographer (the person who operates the ultrasound machine) will assist you as you lie on your back on a padded table. A warm gel will be spread on your chest. The gel improves the ability to send and receive the sound waves between the transducer and your body. The sonographer moves the transducer over your chest to view your heart while frequently changing the position and angle of the transducer. This action guides the sound waves to specific parts of the body so that pictures can be taken. The sonographer may ask you to change positions or hold your breath for short periods of time.

HOW LONG WILL THIS TEST TAKE?
This ultrasound procedure usually takes 60 - 90 minutes to complete.

WHAT WILL I FEEL -- WILL IT HURT?
Usually the ultrasound room lights are turned down to darken the room. This helps the sonographer to see the video screen better. You will feel strong pressure exerted on or between your ribs. This may be uncomfortable but should not be painful.

WHAT WILL THE TEST SHOW?
The test will evaluate the size of your heart and its chambers. It will tell your doctor how well the heart is pumping blood and how well the walls move when the heart is pumping blood. Echocardiograms also tell the doctor how well the valves are working.

HOW DO I GET READY?
No preparation is needed for this exam.
