Q. A patient went to see a cardiologist complaining about being tachycardic. Upon examination, his heart rate was found to be 90 beats per minute; his end-diastolic volume was found to be 140 mL per minute whereas his end-systolic volume was 60 mL per minute. What was his calculated cardiac output per minute?
