[Potential information value of the ultrasonic Doppler cardiographic method in assessing coronary circulation]

The use of ultrasonic Doppler cardiography (with respect to the integral values of the signal at systole) to determine efficient coronary circulation was investigated in acute dog experiments (in comparison to the electromagnetic method) and in biophysical models. On the basis of the comparative studies it is concluded that ultrasonic Doppler cardiography can be applied to measure relative changes in the efficient coronary circulation.
