Final answer:
Echocardiography is a noninvasive mechanism used to measure how well the heart is squeezing and how the valves are working. It uses ultrasound to create images of the heart and provide information about its structure and function.
Step-by-step explanation:
Echocardiography is a noninvasive mechanism used to measure how well the heart is squeezing and how the valves are working. It is a technique that uses ultrasound to create images of the heart and provide information about its structure and function.
Echocardiography works by sending high-frequency sound waves into the body, which bounce off the heart and create echoes. These echoes are then converted into images that can be seen on a screen. By analyzing these images, doctors can assess the heart's pumping action and the functionality of its valves.
For example, if the heart is not contracting properly or if the valves are leaking or narrowed, an echocardiogram can help identify these issues.
