Echocardiography
Echocardiography is a medical imaging technique that uses sound waves to produce images of the heart. A device, called an echo transducer, sends out high-frequency sound waves and then "listens" to the response to create an image based on the sound reflected back at the machine. This visualization allows the cardiologist to determine the size and shape of the heart, in addition to its various functions. Because an echocardiogram does not use x-rays, it is safe to use on women who are pregnant.
What happens during an Echocardiography Examination?
The echocardiogram procedure begins with the patient removing clothing from the upper part of their body and then lying down on the examination table. Electrodes are then placed on the chest and shoulders and attached to the ultrasound machine. An electrocardiogram or ECG is recorded during the examination. A warm, clear gel is then applied to the chest area. This gel allows for consistent contact between the body and the transducer. The echo transducer is pressed firmly against the skin and is slowly moved back and forth across the chest area to allow for the most detailed observation of the heart. The images will appear on the monitor of the ultrasound machine and will be recorded for the cardiologist to review. There are no risks associated with an echocardiogram, and patients can return to their normal activities immediately after the exam. Total exam time is between 20 and 30 minutes.
Echocardiography Preparation
There is no special preparation necessary for an echocardiogram.
