[Experience in the use of the Soviet ultrasonic devices "Ritm" and "Ekran" in cardiosurgical practice]

The study is performed to evaluate opportunities of the echotacho-cardiograph Ritm in detecting the velocify of ventricular wall motions by using the Doppler effect and the echocardioscope Ekran++ that provides display and photography of the heart in the B-mode. In combination with a focusing probe, Ritm is a portable, easy in operation model. When operating with a high frequency recorder it indicates the Doppler signals from different myocardium sites at all stages of the surgical intervention. With the model Ekran++ one can display the heart in real time during surgery as well as evaluate anatomic and dynamic interactions between various cardiac structures that is of great importance in making decisions on surgical tactics and methods.
