Abstract

正

In order to establish a simple and accurate method for the determination ofangiocardiographic ejection fraction （EFa）

the end-diastole

end-systole

the first third andthe first half of the ejection phase on cineventriculograms of the right anterior oblique 30°（RAO 30°） in 42 subjects were analyzed.We found that the percentage of total axisshortening （T%

a） and EFa were in positive correlation.Their linear regression equationis EFa=0.1712+1.3303T%

a （r=0.880） and the quadratic equation is EFa=0.0396+2.4874T%

a 1.9787 （T%

a）

（r

=0.981）.The EF obtained in another 10 subjects by the linearand quadratic regression equations and area-length method are 0.469±0.176

0.464±0.208and 0.482±0.208

respectively.（P

0.05）.It is our opinion that the regression method issimple and the results are positively correlated with the area-length method.It can be usedas a new method for calculating EFa.
