A trained technician performs
the test. A transducer (an instrument that transmits high-frequency
sound waves) is placed on your ribs near the sternum and directed
toward the heart. The transducer picks up the echoes of the waves
and transmits them into an electrical impulse and relays it to an
echocardiogram machine where the impulse is displayed and recorded.
If the echocardiogram is unclear due to a barrel chest, congestive
obstructive pulmonary disease ( COPD ) or obesity , your health care
provider may choose to perform a transesophageal echocardiogram.
In this situation the back of your throat is anesthetized and a
scope is inserted down your throat. On the end of the scope is an
ultrasonic device that is used to get a two dimensional
echocardiogram of your heart.
There is no special preparation
for the test.
Conductive gel is placed on
your chest. The transducer is placed directly on your chest. There
may be pressure on your chest from the transducer. You may be asked
to breathe in a certain way or to inhale a medication to dilate the
blood vessels. You must remain still during the test.
There are no known risks
associated with this test.
This procedure is performed to
evaluate the valves and chambers of the heart in a noninvasive
manner, to aid the diagnosis of cardiomyopathies, to detect atrial
tumors or pericardial effusions (abnormal fluid collection around
the heart), or to evaluate cardiac wall motion and function after a
heart attack .
A normal echocardiogram reveals
normal heart valves and chambers, and normal heart wall movement.
Abnormal results may indicate
heart valve disease, cardiomyopathy , pericardial effusion , or
other cardiac abnormalities.
