Detailed explanation-1: -An echocardiogram uses sound waves to show how blood flows through the heart and heart valves. Sensors attached to the chest and sometimes the legs check the heart rhythm during the test. The test can help a health care provider diagnose heart conditions.
Detailed explanation-2: -Echocardiography uses very high frequency sound waves (ultrasound), which are inaudible to human ears. Sound waves are forms of pressure wave; they can travel through any medium. In echocardiography these waves are generated and detected by means of a piezoelectric crystal contained within a transducer.
Detailed explanation-3: -Doppler echocardiography. This Doppler technique is used to measure and assess the flow of blood through the heart’s chambers and valves.
