Ejection Fraction (EF) Calculator
- About This Calculator
Ejection Fraction (EF) menggambarkan persentase darah yang dipompa ventrikel kiri setiap siklus. Perhitungan ini menggunakan rumus: EF = (SV / EDV) × 100. Pada konteks klinis, EF menjadi salah satu indikator utama fungsi sistolik ventrikel kiri. Nilai ≥ 50% dianggap normal, 40–49% menunjukkan mild LV dysfunction, dan < 40% mengarah pada reduced EF yang sering terkait dengan heart failure dengan fenotip HFrEF.
