echocardiogram
Ultrasound examination of the heart to assess structure and function non-invasively.
Full Definition
An echocardiogram is a non-invasive imaging study that uses ultrasound waves to create real-time images of the heart's structure and function. It can assess ventricular function, valve morphology and function, wall motion abnormalities, and detect pericardial effusion or masses. Various techniques include transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and stress echocardiography. Doppler studies can evaluate blood flow patterns and estimate pressures within cardiac chambers. Echocardiography is essential for diagnosing heart failure, valvular disease, and monitoring treatment response.
Usage
Usage note: Clearly distinguish from ECG (electrocardiogram) in documentation.
