An increase in afterload will result in a(n)
a. decrease in heart rate.
b. increase in heart rate.
c. decrease in stroke volume.
d. increase in cardiac output.
e. increase in stroke volume

Option C.

Explanation:

Afterload is defined as the pressure exerted by the heart that work against to eject blood during systole or ventricular contraction.

Afterload is said as proportional to the average arterial pressure. when systemic vascular resistance and aortic pressure are increased, that results increase in afterload by ventricular dilation and by aortic valve stenosis. As a result in the increased afterload, there is an increase in end-systolic volume and a decrease in stroke volume.

Hence, the correct option is C.

read the excerpt from "the tell-tale heart.”

object there was none. passion there was none. i loved the old man. he had never wronged me. he had never given me insult. for his gold i had no desire. i think it was his eye! yes, it was this! he had the eye of a vulture—a pale blue eye, with a film over it. whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—i made up my mind to take the life of the old man, and thus rid myself of the eye forever.  

read the excerpt from "the black cat.”

beneath the pressure of torments such as these, the feeble remnant of the good within me succumbed. evil thoughts became my sole intimates—the darkest and most evil of thoughts. the moodiness of my usual temper increased to hatred of all things and of all mankind; while, from the sudden, frequent, and ungovernable outbursts of a fury to which i now blindly abandoned myself, my uncomplaining wife, alas! was the most usual and the most patient of sufferers.
