What is??

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

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.

How did u calculate that sir???

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)

My old echo result. Is it okay ??
L.V.end diastolic.      50
L.V end systolic.       34
Left atrium.               32
Aortic root.                33

Yes, EF is a measurement of systolic function. EF is percentage of the blood pumped out of the heart. Normal is above 50%

Meant to write one not obe
