calculaon model selected in the customizaon sengs.
A rst iteraon for the volume is calculated with the selected volume method. The volume displayed in
the report is corrected with a regression formula.
Indexed values can be calculated when the paent’s demographic informaon is available.

Ejecon Fr
acon (EF) The Ejecon Fracon is calculated
based on the ED Volume and the ES
Volume.
EF (%) = (EDV-ESV) ÷ EDV × 100%
Cardiac Output This item indicates the amount of
blood that the heart pumps through
the circulatory system in a minute. The
Cardiac Output is calculated as the
Stroke Volume mes the heart rate in
Beats Per Minute.
Cardiac Output (l/min) = Stroke Vol-
ume ÷ 1000 × BPM
Cardiac Index The Cardiac Index is the Cardiac Out-
put indexed with Body Surface Area
