Echocardiograms are a type of diagnostic test that uses sound waves to create images of the heart. Synonyms for echocardiograms may include cardiac ultrasound, cardiac sonography, echocardiography, and heart ultrasound. These terms are often used interchangeably to refer to the same diagnostic test. Echocardiograms are important tools in the diagnosis and management of various heart conditions, including heart valve problems, cardiovascular disease, and heart failure. Regular echocardiograms may be recommended for individuals with known heart conditions or risk factors for heart disease. Consulting with a healthcare provider can help determine whether an echocardiogram or other diagnostic test may be recommended.
