This test is used to check and monitor the heart and valves' function. A cardiologist can also use it to assess blood flow in the blood arteries and monitor the heart's pumping chambers.
An echo uses high-frequency sound waves that bounce off different areas of the heart, similar to how an ultrasound does. As a result, high-quality images are produced and shown on a screen.
This is a non-invasive and painless diagnostic method for the heart. The echo can be coupled with Doppler ultrasonography and colour Doppler scans for added clarity, depending on the heart disease being tested for.
