- 8. a medical condition in which the heart is enlarged
- 10. an accumulation of cholesterol and calcium in the walls of an artery
- 12. – a medical condition in which the blood pressure in arteries is too high
- 14. any abnormal electrical activity in the heart
- 16. the part of an EKG when the ventricles repolarize (two words)
- 17. a term describing hardening of the arteries
- 19. the part of an EKG when the ventricles depolarize and contract (two words)
- 21. a blood vessel that returns blood to the heart
- 23. also called the mitral valve (two words)
- 24. a group of cells in the right atrium that establishes the heart rate and initiates the impulse (two words)
