An ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat). It can refer to the cardiac atrium, ventricle, gall bladder, or leg veins, although if unspecified it usually refers to the left ventricle of the heart. EF is widely used as a measure of the pumping efficiency of the heart and is used to classify heart failure types. It is also used as an indicator of the severity of heart fa… http://www.tnecho.com/view/45/simpsons-ejection-fraction-/

Som framgår ovan kan Simpsons metod användas för att beräkna både volymer och ejektionsfraktion. Benämningen biplan innebär att mätningarna görs i två plan, nämligen A4C och A2C. Formeln för ejektionsfraktion är: EF (%) = [ (EDV–ESV)]/EDV·100 schwefelhexafluorid formel https://kathurpix.com
