Echocardiography uses ultrasound to visualize the heart in real time, showing how blood moves through the chambers and across the valves. It also assesses how well the ventricles fill and pump (including measurements like ejection fraction) and can reveal wall motion abnormalities, chamber sizes, and valvular function. This makes it especially useful in heart failure to gauge pumping efficiency and structural issues contributing to symptoms.

It does not directly reveal blockages in the coronary arteries (that’s what coronary angiography or CT angiography are for), nor is it limited to valve anatomy alone (valves are seen, but the test also evaluates overall chamber function and flow). It also does not measure electrical activity (that's obtained with an ECG).
