Glossary of Terms
An Echocardiogram, or Echo, is a non-invasive test that translates sound waves from your chest into pictures of your heart. It provides information about how the heart is pumping, how blood is flowing in the heart and blood vessels, how large the heart is, and how the valves are working. It is commonly described as an ultrasound of the heart. If a defect in the heart's structure or mechanical function is causing problems, an echo can often determine the cause of it.
