What Effect, If Any, Would Persistent Tachycardia Have on Cardiac

question 41

Multiple Choice

What effect, if any, would persistent tachycardia have on cardiac output and why?

• A) It would have little or no effect because cardiac output is related to stroke volume, not heart rate.
• B) It would decrease cardiac output because filling time is decreased, which decreases stroke volume.
• C) It would increase cardiac output because tachycardia increases contractility, which increases stroke volume.
• D) It would have little or no effect on cardiac output because tachycardia does not affect preload, afterload, or contractility.
