Can junior emergency physicians use E-point septal separation to accurately estimate left ventricular function in acutely dyspneic patients?

Objectives: The authors determined if E-point septal separation (EPSS) as measured by junior emergency physicians (EPs) correlated with visual estimation of left ventricle ejection fraction (LVEF) by senior EPs and cardiologists in acutely dyspneic patients presenting to an adult emergency department (ED).

Methods: Acutely dyspneic patients were enrolled in a prospective, observational study. EPSS was measured using bedside ultrasonography by junior EPs (PGY 3 and PGY 4 residents) with variable ultrasound experience.
