Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [ 1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the ...
