Pluralechocardiographies
- 1The use of ultrasound to produce images of the heart, especially as a study performed with cardiology-specific equipment and training.
The cardiologist ordered echocardiography to assess the patient's valve function.
Echocardiography revealed a small defect in the wall between the heart's chambers.
Note
Built from echo and cardiography, the word describes a heart drawn by its echoes, the reflected sound of ultrasound. In clinical use it marks territory. It names the dedicated cardiology study, with its own equipment and trained operators, as distinct from POCUS, the point-of-care ultrasound that any clinician may turn on the heart. It is uncountable for the discipline but also countable, so separate studies are echocardiographies.
