A standard echocardiogram (echo), also known as a transthoracic echocardiogram (TTE), is an imaging technology that uses ultrasound to create images of your heart. It is a diagnostic test used to examine the heart and its blood supply, determine how large the heart is, how well it contracts, and how the valves function.
An ultrasound probe is placed on the patient’s chest (thorax) and high frequency sound waves are used to create images of the heart. Doppler technology can also be used to analyze the speed and direction of blood flow. The images are displayed on a monitor and are digitally recorded.
