Echocardiogram
Definition An echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image and involves no radiation exposure. Why the Test is Performed This test is performed to evaluate the valves and chambers of the heart in a noninvasive way. The echocardiogram allows doctors to diagnose, evaluate, and monitor:
How the Test is Conducted A cardiologist or specially trained sonographer performs the test. You will be asked to remove your clothes from the waist up and lie on an examination bed. Electrodes will be placed on your chest to allow for monitoring your heart rate and rhythm. An instrument called a transducer that transmits high-frequency sound waves is placed on your ribs near the breast bone. A transducer gel will also be used to obtain the images. This may be cold and is water based. It washes off easily at the end of the test. Additional images will be taken at the left lower chest. 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. The Doppler probe records the motion of the blood through the heart. An echocardiogram allows doctors to see the heart beating, and to see many of the structures of the heart. The result will be discussed with you at the end of the test. How to Prepare for the Test There is no special preparation for the test. Risks There are no known risks associated with this test.
