Echocardiogram
Cardiac echocardiograms (ECHOs) may be ordered if your doctor suspects a problem
with the heart muscle, heart
valve disease, or coronary
artery disease. An ECHO examines the heart using ultrasound technology.
Harmless and painless sound waves are bounced off the heart, and the returning
signals are converted into a moving image on a video screen. There are several
types of echocardiograms.

Transthoracic Echocardiogram
(TTE)
During a transthoracic (through-the-chest) ECHO, a wand (transducer) sends sound
waves to the heart as it is moved over your skin on the chest area. Images of
the front and sides of the heart are produced.
Exercise Stress Echocardiogram
A transthoracic ECHO is performed, providing an image of how the heart functions
at rest. A second ECHO is taken after a period of exercise, providing an image
of how the heart functions with an increased workload.
Dobutamine Stress
Echocardiogram
This test provides the same effect as an exercise stress ECHO, except that
instead of exercise, the heart’s workload is increased by a medication
that simulates exercise. This is particularly beneficial for people with
physical limitations.
Transesophageal Echocardiogram
(TEE)
During a transesophageal (through-the-throat) ECHO, an ultra-small transducer is
placed on the tip of a very thin, flexible tube and placed down the throat,
through the esophagus, which lies directly behind the heart. Sound waves are
emitted from the transducer, providing images of the back of the heart
(unavailable with a transthoracic ECHO).
