An echocardiogram is a safe, non-invasive test used to identify and monitor different heart conditions. Detailed images are produced on a computer screen by placing a transducer on the patient's chest, which emits high-frequency sound waves that bounce off the heart. With these images, medical professionals can assess the structure and operation of the heart. This includes its chamber size and shape, wall thickness and motion, and blood flow through its valves and vessels.   Echocardiograms can also be used to evaluate heart function in patients with known or suspected heart disease, assess heart function during exercise or medication-induced stress tests, or track the development of heart conditions over time. Depending on the type of echocardiogram being performed, the procedure usually lasts 30 to 60 minutes and is painless.   Overall, echocardiogram testing is a useful method for identifying and treating heart disease that assists medical professionals in creating effective treatment plans.
