Cardiac point-of-care ultrasound (POCUS) is a non-invasive bedside imaging technique used to evaluate the structure and function of the heart in real-time. It allows healthcare providers to quickly assess cardiac function and diagnose a variety of cardiac conditions, such as pericardial effusion, valvular disease, and myocardial infarction. Cardiac POCUS is particularly useful in emergency and critical care settings where rapid diagnosis and treatment are crucial. The technique is safe, cost-effective, and can be performed by healthcare providers with proper training.
