This is the same technology which is used so extensively in man to examine the heart as well the abdominal viscera and the pregnant uterus. Echocardiography may be divided into three types based on the instrumentation and application. This is the oldest form of echocardiography. It was introduced into Veterinary Medicine in the late 1970's. It is more specifically known as the Time Motion Mode .
