What is echocardiography?

Echocardiography is a non-invasive ultrasound examination of the heart, which allows healthcare providers to visualize the heart's structure and function in real-time. This imaging technique uses sound waves to create detailed images of the heart's chambers, valves, and surrounding blood vessels. It is particularly useful for assessing heart conditions such as valve disorders, cardiomyopathy, and congenital heart defects.

The use of ultrasound means that there are no risks associated with radiation exposure, making it a safe method for both diagnostic and monitoring purposes. The detailed images obtained can help physicians make informed decisions about treatment and management of heart-related issues.

By contrast, the other answer choices involve different procedures or concepts. Surgical procedures on the heart imply invasive techniques, such as operating on the heart, which echocardiography definitely is not. A type of electrocardiogram relates specifically to measuring the electrical activity of the heart, which is different from capturing structural images via ultrasound. Finally, measuring blood pressure is a distinct procedure and does not relate to imaging the heart itself.
