Basic Facts:

  • An echocardiogram is a test that uses high-frequency sound waves to assess the structure and function of the heart, to measure pressures inside the heart, and to measure the direction and speed of blood flow. 
  • Transthoracic echocardiogram (often shortened to just "echo") is an ultrasound of the chest wall.
    • TEE, or transesophageal echocardiogram, is invasive, performed at a hospital under sedation.
    • Stress echo involves an echo before and immediately after a stress test.
  • No radiation is used. It is a painless, non-invasive way to screen or asses for heart disease.
