What effect does ventricular tachycardia have on cardiac output?
A) Increases cardiac output due to an increase in ventricular filling time
B) Decreases cardiac output due to a decrease in stroke volume
C) Increases cardiac output due to an increase in preload
D) Decreases cardiac output due to a decrease in afterload

Question

Quizplus · Accepted Answer

Tachycardia is detrimental to anyone with ischemic heart disease because it decreases the time for ventricular filling,decreases stroke volume,and compromises cardiac output.Tachycardia increases heart work and myocardial oxygen demand while decreasing oxygen supply by decreasing coronary artery filling time.
