QuestionChoice
Cardiac output is calculated with the following equation:

Cardiac output (CO) = Stroke Volume (SV) x Heart Rate (HR)
CO = SV x HR

Stroke Volume (SV) = End-diastolic volume (EDV) - End-systolic volume (ESV)
SV = EDV - ESV

For this patient:
SV = 100mL - 75mL
SV = 25mL

CO = 25mL x 136bpm
CO = 3400mL/min
CO = 3.4L/min

A 78-year-old man presents to the Emergency Department with a heart rate of 136 bpm. After doing an echocardiogram, his end-diastolic volume is 100mL, with an end-systolic volume of 75mL.

What is this patient's cardiac output in litres/minute?
