An echocardiogram (echo) is an ultrasound of the heart which uses high-frequency sound waves to make pictures of your heart. The test is also called diagnostic cardiac ultrasound.
This test demonstrates the heart’s structure and function and shows your doctors how the valves inside your heart are working. Echo tests can be used to evaluate how various diseases may affect the heart such as high blood pressure, heart disease, heart failure, stroke, cancer and more. An echo test is a tool we use to care for many of your common medical conditions.
