Which of the following will NOT increase stroke volume?

Question

Quizplus · Accepted Answer

Increased end-systolic volume means that there is more blood remaining in the ventricle after contraction, which should decrease stroke volume. A, B, and D would all increase stroke volume - increased end-diastolic volume allows for a greater stretch of the cardiac muscle fibers and therefore a more forceful contraction, increased contractility increases the force of contraction, and increased stretch of the cardiac muscle fibers during ventricular filling allows for a greater forceful contraction.
