  2. The AVR, AVL, and AVF leads are called?
    Augmented Leads
  3. What is the term used to refer to the ECG that is within normal limits?
    Normal Sinus Rhythm (NSR)
  4. Arrhythmia
    Abnormal heart rate, rhythm, and conduction system
  5. The flat horizontal that separates the various waves is known as the?
    baseline, or isoelectric line
  6. The most common nonmedical term for a myocardial infacrtion is?
    heart attack
  7. The cardiac stress test (treadmill) is?
    Exercise electrocardiography that is done to determine if the heart is reciiving enough blood during exercise
  8. What are augmented leads?
    Leads that measure cardiac activity from one electrode on the body at a time.
  9. What are artifacts?
    Unwanted changes in an ECG tracing caused by movement, machine malfunction, or other factors
  10. Name the heart condition in which the heartbeat is too rapid, and give the heart rate.
    Sinus tachycardia, 100 to 180 beats/min
  11. A device on the skin that picks up electical impules given off by the heart is known as an?
  12. What is the name given to the modified myocardial cells that set the pace of the heart?
    SA Node
  13. Stylus
    Heated device that records the heart's activity on heat-sensative graph paper
  14. ECG
    Graphic picture of the hearts electircal activity
  15. Wandering baseline
    Shift on the ECG tracing from the baseline or center of the paper
  16. Amplifier
    Device on the electrocardiograph that magnifies or enlarges the heart's electrical impulses so they can be recorded
  17. Alternating current
    Electrical intereference that appears as small, uniform spikes on ECG tracing
  18. Baseline
    The flat horizontal that separates the various waves
  19. Pacemaker
    Device that delivers electrical impulses to the heart muscle when the SA Node is unable to do so.
  20. Ventricular Tachycardia
    Three or more consecutive PVCs with heart rate exceeding 100 beats per min
  21. U-Wave
    Normal, small upward curve that occassionally follows a complete ECG cycle after the PQRST; has unknown indication
  22. Ischemia
    Poor blood supply to body tissue causing a lack of oxygen to that tissue
  23. Cardiac Cycle
    one heartbeat, one contraction/relaxation phase of the heart
  24. Premature Atrial Contraction (PAC)
    Conditioin in which an electrical impulse in the atria starts before the next expected heartbeat
  25. Arrythmia
    Abnormal heart rate, rhythm, and conduction system
