Principles of Doppler Echocardiography and the Doppler Examination #1

Doppler echocardiography is a method for detecting the direction and velocity of moving blood within the heart. As will be seen in this program, the technique may be used for detection of cardiac valvular insufficiency and stenosis as well as a large number of other abnormal flows. The current interest in Doppler echocardiography has reached a remarkable level in just the past few years. Doppler methods extend the use of cardiac ultrasound into the evaluation of normal and abnormal flow states and provide quantitative data that are essential in the clinical decision making process concerning patients with heart disease.
