1. Average adult resting heart rate 70 beats/min and stroke volume = 70 ml/beat. What is an average adult's resting cardiac output? 2. How would the following affect the CO? (use up arrow for increase and down arrow for decrease) exercise Coronary artery disease hyperthyroidism pregnancy 3. J.R. experienced a heart attack that damaged the left ventricular myocardium. How would this affect his cardiac output (CO) assuming the heart is unable to compensate? What symptoms would J.R. experience due to this change in CO? How would his heart try to compensate to bring CO back to normal? 4. During intense exercise, S.L.'s heart rate increased to 140 bpm and her stroke volume increased to 180 ml. What is S.L.'s cardiac output during exercise? Why does S.L.'s CO need to increase during exercise? 5. Runner Usain Bolt has a resting heart rate of 33 bpm yet his cardiac output was the same as an average person. What is Usain Bolt's resting SV? How can his heart achieve this SV? 1.
