Given a stroke volume of 40 ml and an end-diastolic volume (EDV) of 70 ml, what is the pa-tient's ejection fraction (EF)?
 
  a. 0.57
  b. 1.75
  c. 67
  d. 2800

Question 2

Stroke volume can be calculated using which formula?
 
  a. Ejection fraction  heart rate
  b. End-diastolic volume  end-systolic vol-ume
  c. Ejection fraction  end-systolic volume
  d. Cardiac output  end-diastolic volume

Answer to Question 1

ANS: A
Given a stroke volume of approximately 40 ml, and an EDV of 70 ml, the ejection fraction can be calculated as follows:
EF = SV/EDV= 40 ml/70 ml = 0.57, or 57.

Answer to Question 2

ANS: B
Stroke volume = EDV  ESV.
