• A sedative along with an anaesthetic is given to numb the throat, so that the patient is comfortable during the test.
• A scope down the esophagus is inserted, as it carries a device that sends sound waves out.
• This method gives a clearer picture of the heart than TTE.
• This is the one mostly used. Here a transducer is placed on the ribs that are near the breastbone and then is directed to the heart. This device, which sends sound waves of high frequency, is moved to different locations on the abdominal wall and the chest.
• The sound wave echoes are picked up by the transducer and then transmitted as electrical impulses, which are converted into moving pictures by the echocardiography machine. Still pictures are taken too.
• The blood-motion through the heart is recorded by a Doppler Echocardiogram.
• In case the sound waves are blocked by the Chest Wall bones, lungs, body tissue, or ribs, resulting in lack of clarity in the pictures, a little amount of liquid might be injected by the cardiographer.
