Echocardiogram (Ek-oh-car-dee-oh-gram) is another way to take a picture of your heart. You will only have this test done if you didn’t have the Cardiac MRI test (see above). This test uses sound to make a fuzzy picture of your heart. You can’t hear the sound, but the machine can. The machine uses sound bouncing off your heart to make pictures.
This works sort of the way a bat can “see” in the dark. Bats make sounds when they fly. They hear echoes when those sounds bounce off things. The echoes help the bats know where things are. Echocardiogram works like that. It does not hurt.
