what is an echocardiogram
Sonographer doing pediatric echocardiography. Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. An echocardiogram, often referred to as a cardiac echo or simply an echo, is a sonogram of the heart. (It is not abbreviated as ECG, because that is an abbreviation for an electrocardiogram.) Echocardiography uses standard two-dimensional, three-dimensional, and Doppler ultrasound to create images of the heart.
