An echocardiogram (echo=sound + card=heart + gram=drawing) is an ultrasound test that can evaluate the structures of the heart, as well as the direction of blood flow within it. Technicians specially trained in echocardiography produce the images and videos, often using a special probe or transducer that is placed in various places on the chest wall, to view the heart from different directions.
What is an echocardiogram? An echocardiogram is one of the most common diagnostic tools cardiologists use to visualize the heart, aorta, and other blood vessels. An echocardiogram is essentially a Doppler ultrasound tool. The device emits sound waves, which bounce off the heartâs structures, creating an image of the heart and/or blood vessels under examination.
