Chapter 19, Problem 3TYR

Assume that one ventricle of a child’s heart has ail EDV of 90 mL, an ESV of 60 mL, and a caidiac output of 2.55 L/min. What are the child’s stroke volume (SV), ejection fraction (EF), and heart rate (HR)?

1. a. SV = 60 mL; EF = 33%; HR = 85 bpm
2. b. SV = 30 mL; EF = 60%; HR = 75 bpm
3. c. SV = 150 mL; = 67%; HR = 42 bpm
4. d. SV = 30 mL; EF = 33%; HR = 85 bpm
5. e. Not enough information is given to calculate these.
