How does a heart ultrasound work?
A doctor has provided 1 answer
Echocardiogram: Acoustic waves (in the mega-hz so they can't be heard) are sent from the probe and the time the reflected wave takes to return is measured. This is similar to sonar. For moving structures, like valves and blood, the machine takes advantage of the doppler effect (notice the change in tone of the train whistle as it passes a station) to measure velocities.
