Abstract

During the past several years and in cooperation with our cardiology colleagues, we have attempted to perfect a method of determining left-ventricular ejection fraction that can be applied in the evaluation of patients with left-ventricular dysfunction. It might be helpful to remember that ejection fraction is one method of estimating left-ventricular performance and describes the percentage of LV blood that is ejected with each systolic contraction (ejection fraction equals stroke volume/end-diastolic volume).
