1. Systole Phase of contraction when blood is ejected

2. Diastole Phase of relaxation or filling

3. Conduction Sys-
tem




4. Inherent Rate of 60-100 beats per minute
SA node

5. Inherent Rate of 40-60 beats per minute
AV node AV node acts as a "gate keeper" for ventricles

6. Inherent Rate of 40-60 beats per minute
Bundle of His

7. Inherent Rate of 20-40 beats per minute
Ventricles

8. Sympathetic Ner- Affects atria & ventricle, increases SA node rate, speed
vous System of conduction, and force of contraction

9. Parasympathetic Affects the atria, decreases the HR, decreases the speed
Nervous System of conduction, decreases for of contraction

10. Depolarization Cells receive a stimulus, changes in electrical charges
occur resulting in a electrical flow which spreads in a
wavelike motion resulting in contraction - systole

11. Repolarization Return of the electrical charge to their original postion,
recovery state

12. Absolute Refrac- Portion of the cardiac cycle where NO stimulus, no matter
tory how strong, can excite the cardiac tissue

13. Relative Refracto-

Portion of cardiac cycle when all cells are not fully repo-
larized, a strong enough stimulus can excite the cardiac
tissue, also referred to as the vulnerable period

14. Positive Deflec- Current flowing toward a + electrode gives a + deflection
tion (above baseline)

15. Negative Deflec- Current flowing away from a + electrode gives a - deflec-
tion tions (below baseline)

16. P wave Reflects atrial depolarization

17. PR interval Represents the interval from the time the impulse leaves
the SA node, the delay at the AV node.

18. QRS Represents ventricular depolarization. The time required
for the impulse to travel through R & L ventricles

19. Normal PR inter- 0.12-0.20 seconds
val

20. Normal QRS 0.04 -.10 or <0.12

21. T wave Represents ventricular repolarization

22. QT interval Represents total ventricular activity (depolarization to re-
polarization)

23. ST segment Represents time between completion of ventricular depo-
larization and beginning or repolariation

24. Sinus Rhythm Rate is 60-100, it is regular, normal PR and QRS interval.
One P wave for every QRS

25. Normal Sinus
Rhythm

26. Sinus Bradycar- Rate is < 60, rhythm is regular, P wave for every QRS.
dia May be normal is some people, especially atheletes
