Cardiac output is calculated as the product of stroke volume (SV) and heart rate (HR). Stroke volume is the difference between end-diastolic volume (EDV) and end-systolic volume (ESV), so SV = EDV - ESV = 85 mL - 35 mL = 50 mL. The cardiac output (CO) = SV * HR = 50 mL * 50 = 2500 mL/min, or 2.5 L/min.
