Jon-Emile S. Kenny MD [@heart_lung] The left ventricular ejection fraction [LVEF] is a commonly-sought cardiac measure. With the explosion of bedside ultrasound and automated methods to capture LVEF, the ejection fraction will grow in clinical prominence and affect decisions for the acutely-ill. Asked the meaning of the LVEF, many clinicians might describe it as a ‘measure of cardiac function’ – but this is a nebulous answer. Does ‘cardiac function’ mean the contractile or
