  1. An electrocardiogram is a recording of the?
    Heart's electrical activity
  2. The AVR, AVL, and AVF leads are called?
    Augmented leads, or unipolar 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; also called dysrhythmia.
  5. The flat horizontal line that separates the various waves is known as the?
    Baseline, or isoelectric line
  6. The most common nonmedical term for a myocardial infarction is?
    Hear Attack
  7. The cardiac stress test (treadmill) is?
    Exercise electrocardiography that is dont to determine if the heart is recieving enough blood during exercise
  8. Wha are your augmented leads?
    • Right Arm (AVR)
    • Left Arm (AVL)
    • Left Foot (AVF)
  9. What are artifacts?
    Unwanted changes in an ECG tracing caused by ovement, machine malfunction, or other factors
  10. Name the heart condition in which the heartbeat is too rapid, and give the heart rate.
    • Sinus Trachycardia
    • -100 to 180 beats/min
  11. A device on the skin that picks up electrical impulses given off by the heart is known as an?
    Electrode(s)
  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 heart's electrical 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 enarges the heart's electrical impluses so they can be recorded.
  17. Alternating current
    Electrical interference that appears as small, uniform spikes on ECG tracing
  18. Baseline
    Line that separates the various cardiac 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 minute.
  21. U-Wave
    Normal, small upward curve that occasionally follows a complete ECG cycle after 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 pf the heart
  24. Premature Atrial Contraction
    Condition in which an electrical impulse in the atria starts before the next expected heartbeat.
  25. Arrythmia
    Abnormal heart rate, rhythm, and conduction system; also called dysrhythmia.
