A person went to a cardiologist complaining about being tachycardic. Upon examination, his heart rate was 100 beats per minute; his end-diastolic volume was 100 mL, whereas end-systolic volume was 40 mL, whereas end-systolic volume was 40 mL. what was his calculated cardiac output per minute?

View answer and explanation

Correct option: C

6 L

Option C (6 L) is correct because stroke volume is the difference between end-diastolic and end-systolic volumes (100 mL - 40 mL = 60 mL). Cardiac output is stroke volume multiplied by heart rate, so cardiac output = 60 mL/beat * 100 beats/min = 6000 mL/min = 6 L/min.
