The use of ultrasonic reflectoscope for the continuous recording of the movements of heart walls.

1) It has been shown that it is possible to locate blood-heart wall boundaries by the supersonic reflectoscope method using frequencies of about 2.5 Mc. 2) The method was applied for the locating of heart walls on living human beings and continuous registration of movements of the heart walls was found possible. 3) Recordings are shown of the movements of the left ventricle wall in the normal and in the diseased heart. Further, movements of the left atrial wall in mitral stenosis were recorded. © 2004 Blackwell Publishing Ltd.
