ABSTRACT
Rapid and accurate evaluation of unstable patients presenting with symptoms suggestive of cardiovascular pathology is a crucial task in a busy emergency department (ED). A focused history taking, physical examination, and 12-lead electrocardiogram (ECG) remain essential first steps of guideline-proposed algorithms, but additional laboratory tests and imaging studies are required in a sizeable number of patients. Among the currently available imaging techniques, echocardiography seems perfectly fitted for demanding emergency settings because of its availability, portability, and accuracy. It can be performed promptly virtually everywhere, and the results of examination are immediately available, allowing initiation of appropriate treatment without unnecessary delay.
