Fuzzy Modeling to Predict Severely Depressed Left Ventricular Ejection Fraction following Admission to the Intensive Care Unit Using Clinical Physiology

Figure 5

Membership functions obtained for assessing severely depressed LVEF. Lower and upper bounds accepted for normal values ranges are also depicted (grey zone). The solid-lined cluster corresponds to the antecedents of Rule 1 () and the dash-lined cluster corresponds to those of Rule 2 ().
