Under normal circumstances, left ventricular shoening fraction (LVSF) is:
Left ventricular shoening fraction (LVSF) is the percentage of shoening of LV fibers from their end-diastolic length (EDL). EDL and ESL are end-diastolic length and end-systolic length, respectively. Normal LVSF = 35%-40%. The value of LVSF decreases in LV failure.
