Questions and Answers

What is the formula for calculating cardiac output?

  • Cardiac output = stroke volume / heart rate
  • Cardiac output = stroke volume x heart rate (correct)
  • Cardiac output = blood pressure x heart rate
  • Cardiac output = heart rate / stroke volume

    • Which factor refers to the stretch of cardiac muscle prior to contraction?

  • Cardiac output
  • Stroke volume
  • Afterload
  • Preload (correct)

    • What does afterload represent in the context of cardiac function?

  • The volume of blood ejected from the heart per beat
  • The time interval between heart contractions
  • The resistance against which the cardiac muscle must contract (correct)
  • The speed of heart rate
