An increase in arterial blood pressure during systole would cause -
A) a reduction in stroke vol.
B) an increase in the velocity of blood ejection from the ventricles
C) an increase in stroke vol.
D) a reduction of ventricular afterload
E) a decrease in arterial pressure during diastole

a reduction in stroke vol. - increase stroke volume
B) an increase in the velocity of blood ejection from the ventricles - nothing wrong with velocity
C) an increase in stroke vol. - excess sodium increase plazma volume->increase stroke volume
D) a reduction of ventricular afterload -increse
E) a decrease in arterial pressure during diastole- will increase excess sodium->vasoconstriction
The answer is C

The immediate result would be a decrease in stroke volume. Increased afterload (arterial blood pressure as blood is ejected from the ventricle during systole) reduces stroke volume.

decrease in str vol... due to increaed afterload this in turn will INCREASE preload

So what is the answer? I think it has to be decrease in stroke volume.

My answer is A simply because there is resistance to the flow of blood leaving the left ventricle....therefore the decrease in stroke volume.

Needs to be A...this question appears to ask what happens immediately during the increased afterload (since it says during systole), and that is the only one that makes sense.
