Echocardiography or ultrasound of the heart is one of the most common procedures in cardiology. This technology involves sending sound waves into the chest through a probe placed on the skin of the chest wall and generating an image with the returning sound waves that reflect off the structures within the heart.
These sound waves are high frequency and not audible by human ears. The procedure is virtually harmless, involves no X-rays, and poses little or no known risk to a patient other than the discomfort when the probe is gently pressed against the skin of the chest.
The procedure is usually performed by a sonographer. Images are recorded and later interpreted by your provider. The procedure takes about 30-45 minutes and is performed in the office. Depending on the type of echocardiography test conducted, the physicians at Alpharetta and Cumming Internal Medicine can learn about the size, shape, and movement of your heart muscle. This test can also show how the heart valves are working and how blood is flowing through your heart. Echocardiography can also give your provider information about your arteries.
Echocardiography uses high-frequency sound waves (also called ultrasound) that can provide a moving picture of your heart. The sound waves are sent through the body with a device called a transducer. The sound waves bounce off of the heart and return to the transducer as echoes. The echoes are converted into images on a television monitor to produce pictures of your heart.
No special preparation is needed before you have an echocardiogram. During the test, you will lie on an examination table. A sonographer will place small metal disks called electrodes on your chest. These electrodes have wires called leads, which hook up to an electrocardiogram machine. This machine will monitor your heart rhythm during the test.
Next, the sonographer will put a thick gel on your chest. The gel may feel cold, but it does not harm your skin. Then, the sonographer will use the transducer to send and receive the sound waves. The transducer will be placed directly on the left side of your chest, above your heart. The sonographer will press firmly as he or she moves the transducer across your chest. You may be asked to breathe in or out or to briefly hold your breath during the test. But, for most of the test, you will lie still.
