Cardiac Flash Cards

Question 1

Cardiac output Formula:

Answer 1

CO = SV x HR

Question 2

Preload:

Answer 2

Initial stretching of the cardiac myocytes prior to contraction.
(Volume of blood in ventricles at the end of diastole).

Question 3

Afterload:

Answer 3

Resistance to ejection - pressure the L ventricle must pump against.

Question 4

Ejection Fraction:

Answer 4

Amount of blood ejected from the L ventricle during systole.
