# What is??

What is LV systolic function and EF. Are they obe and the same???

Meant to write one not obe
Yes, EF is a measurement of systolic function. EF is percentage of the blood pumped out of the heart. Normal is above 50%
My old echo result. Is it okay ??
L.V.end diastolic.      50
L.V end systolic.       34
Left atrium.               32
Aortic root.                33
You need to provide some more numbers, but what you describe is within normal limits. Your Fractional Shortening is 32% which should equal an EF of 60-65%, normal systolic function. Which should indicate that your heart pumps approx 80 ml pr beat (this is just a fun fact)
How did u calculate that sir???
Hi,

By using some formulas,

Fractional Shortening = (LV End diastolic diameter - LV end systolic diameter) / LV End Diastolic diameter %
Ejection fraction can roughly be estimated as Fractional Shortening x 2.

Stroke volume = End diastolic volume x EF. I don't remember the formula to calculate end diastolic volume, but my LV End diastolic diameter is 52 mm and my LV End diastolic volume is 135-140 ml. I would think yours is 120-125 ml (I can recalculate it if I can find that formula, but it's not important).

125 x 0,64 = 80 ml.
