LOINC long common name : Left ventricular Ejection fraction by US.2D Calculated by Teichholz method;

LOINC short name : LV EF 2D Teichholz;

LOINC description : This term represents the left ventricular ejection fraction (LVEF) based on left ventricular (LV) end-diastolic and end-systolic volumes as calculated by the Teichholz method from measurements taken during 2D cardiac echo. The Teichholz formula is used to calculate left ventricular volume as follows: LV end-diastolic volume [7/2.4 Dd]x[Dd] 3, where Dd the left ventricular internal dimension (short axis) as measured at end-diastole, and LV end-systolic volume [7/2.4 Ds]x[Ds] 3, where Ds the left ventricular internal dimension (short axis) as measured at end-systole.
