An Echocardiogram is a test that uses ultrasound to assess the structure and function of the heart. You will be required to remove all your clothing from the waist up. The Echocardiographer will place some small dots on your chest to monitor your heart rate and place an ultrasound probe and gel at various places on your chest. During the study you will hear noises which reflect the blood flow through your heart. Ultrasound is a safe modality, and does not pose any risks to the patient. The test can take between 30 and 45 minutes and there are no special requirements before the test.
