What is echocardiography:
Echocardiogram is a test that uses sound waves to create a moving picture of the heart.
Why the test is performed:
This test is performed to evaluate the valves and chambers of the heart in a noninvasive manner. The echocardiogram allows doctors to evaluate heart murmurs, check the pumping function of the heart, and evaluate patients who have had heart attacks. It is a very good screening test for heart disease in certain groups of patients.
How to prepare for the test:
There is no special preparation for the test.
How the test is performed:
A trained technician performs the test, then your physician interprets the results. An instrument that transmits high-frequency sound waves called a transducer is placed on your ribs near the breast bone and directed toward the heart. The transducer picks up the echoes of the sound waves and transmits them as electrical impulses. The echocardiography machine converts these impulses into moving pictures of the heart.
