#Shorts What is an Echocardiogram? A more detailed version is available at: [ Ссылка ]
Echocardiogram is an ultrasound imaging of the heart. Ultrasound is high frequency sound wave which is not audible to the human ear. The machine sends out ultrasound beams towards the heart intermittently and listens for the echo. Computer synthesised images are then produced from the echoes received from various parts of the body. It is similar to the location of aeroplanes in the sky by a radar system. Doppler imaging is by analysing the echoes of the ultrasound beam from moving blood cells. You will be familiar with the difference in the sound of a horn of a moving train when it comes towards you and moves away from you. The same principle is applied in Doppler.
