Across
- 3. The right side of the heart receives this type of blood
- 4. This dictates which way the heart valves go
- 7. This type of chamber contains the SA node
- 8. Which ventricle has the thicker wall?
- 10. This will increase when you do strenuous exercise
- 13. Most shortening occurs in this ECG interval
- 14. Blood needs to deliver this to working muscles
- 15. The kind of signal that the SA node fires
- 16. Bottom number in blood pressure
- 18. ECG interval of ventricular depolarization
- 20. The product of stroke volume and heart rate
Down
- 1. Node that contains the pacemaker cells
- 2. Top number in blood pressure
- 5. Can only increase this to a certain point during exercise
- 6. A good way to increase cardiovascular fitness
- 7. These people typically found to have very low HR
- 9. Occurs before repolarization
- 11. The sum total of the electrical activity of the heart
- 12. The larger chambers of the heart
- 17. Left ventricle leads to this
- 19. Interval between peak to peak on an ECG
