dimensions at systole (LVIDs) and diastole (LVIDd).
Stroke Volume (SV)
Stroke volume is the volume of blood pumped by the
heart in a single beat. It is equal to the difference
between the LV end diastolic and end systolic volumes
and is expressed in milliliters.
SV = EDV–ESV(ml).
Ejection fraction (EF)
Ejection fraction is the fraction of blood effectively
pumped out of the heart in one beat. It is equivalent to
the stroke volume divided by end diastolic volume. It is
expressed as a percentage
.

Cardiac output (CO
)
Cardiac Output is the volume of blood pumped by the
heart in one minute. It is equivalent to stroke volume
times heart rate. It is expressed in liters per minute
