Sir , On 26 May i underwent Echocardiogram. Echo Report attached herewith. I have a confusion. IN THE REPORT THE EJECTION FRACTION IS 57%. But when i searched online the formula to calculate EJECTION FRACTION is:- EF=(EDV-ESV)/EDV x 100 When i apply the respective values of EDV n ESV mentioned in the attached echo report in the formula then is get the EF-53%(calculation below) EF= (103-48)/103 = 0.533 x 100 = 53.3% I went to radiologist and raised the same question. He told me that we don't calculate the Ejection Fraction manually and the mentioned figure of EF=57% is automatically calculated by AI of the Colour Droppler Sonography machine. He also told me that the Heart Rate(92 BPM) also plays an important role in calculating the EF through. Sir, Now my question does HR(92) play any role in calculating EF? And does today's Echocardiogram machine ( GE Electric) automatically calculate EF? Does EF varies from Lab to Lab?
