Definition:A calculated measurement corresponding to the ratio or percent reduction in left ventricular diameter between end-diastole and end-systole. Can be calculated as the left ventricle end-diastolic diameter (LVDd) minus the left ventricle end-systolic diameter (LVSd) divided by the left ventricle end-diastolic diameter (LVDd) with the quotient multiplied by 100, i.e. FS = [(LVDd-LVSd)/LVDd] x 100.
