From: Septic cardiomyopathy
Relationship between left ventricular (LV) ejection fraction (x axis) and cardiac index (y axis) in 183 patients with septic shock who underwent echocardiography. Providing that depressed LV intrinsic contractility is constant, the relation may be separated into four parts according to systemic vascular resistance, volemia, and right ventricular (RV) function. Size of the circles is related to LV end-diastolic volume, from 35 for the smallest to 135 ml for the biggest.
