Which of the following would NOT result from an increase in ventricular contractility?
A) increased ejection fraction
B) increased proportion of end -diastolic volume that is ejected
C) increased stroke volume
D) decreased end -systolic volume
E) decreased end -diastolic volume

Question

Quizplus · Accepted Answer

An increase in ventricular contractility leads to increased ejection fraction, increased proportion of end-diastolic volume that is ejected, increased stroke volume, and decreased end-systolic volume, as the heart pumps more efficiently. However, it does not directly lead to a decrease in end-diastolic volume, which is determined by factors such as venous return and filling time.
