Module 3

2. the absence of cardiac activity
4. damage or interference in the electrical pathway through the septum altering the contraction of the ventricles
8. slow heart rate
9. the portion of waveforms in an EKG tracing located above the isoelectric line
12. relaxation phase of the heart that prepares the heart for another depolarization
13. measured or estimated by reviewing the EKG tracing and using various techniques and formulas
14. decrease in oxygenation of tissues due to poor blood flow
16. gain or voltage
17. straight line on the EKG tracing between cardiac cycles where no electrical activity of the heart is being conducted and no deflection is noted
18. ischemia leading to death of heart muscles tissue also known as heart attack
19. death of tissue due to a lack of oxygenation, usually due to a blockage in circulation

1. the excitement of the atrial with a rise in internal pressure to forcefully push blood into the ventricles
3. the downward presentation of waveforms on the EKG tracing that is located below the isoelectric line
5. the absence of any electrical activity in the heart
6. complex process involving the opening of sodium and potassium channels on the surface of cardiac cells resulting in the loss of polarity.
7. an instrument that is useful in measuring distances on an EKG tracing
10. rapid wave-like contractions
11. heart rate
15. state of quivering with no organized contraction
