[Physical principles of the Doppler echocardiography determination of heart minute volume].
By means of Doppler echocardiography to measure blood flow velocity in the aorta and echocardiographic imaging to measure vessel diameter cardiac output can be assessed noninvasively in selected patients. This paper presents the underlying physical principles and discusses resulting aspects of measurement and limitations of the technique.
