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

An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat. raymour and flanigan playaAn 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.
