Which of the following ECG/EKG graphs appears normal?

A.  Calculate stroke volume if end diastolic volume (EDV) is 135 ml/beat and end systolic volume (ESV) is 65 ml/beat. Show your work. Remember to include the units in your answers! Bold or highlight your final answer. B.  Using the necessary numbers from question A, calculate cardiac output (CO) if HR = 65 bpm. Show your work. Remember to include the units in your answers!  Bold or highlight your final answer. 

Why would stroke volume increase if the heart rate slows down?  Explain in 1-3 sentences, please.
