1. ST segment elevations with reciprocal changes has a higher sensitivity and specificity for AMI than ST elevation alone.

    True
    False
2. A negative QRS in Lead I and a positive QRS in aVF gives an axis in what quadrant?
    LAD
    ERAD
    RAD
3. Significant Q wavs are indicated by all of the following accept:
    large downward QS deflection in aVR
    Q wave > 0.03 seconds in duration
    q wave > one third the height of the QRS
4. In the adult patient in cardiac arrest, a twelve lead ECG:
    has no real value and can waste valuable time
    Is valuable to detect occult Vf
    can diagnose AMI in VT or Vf
5. A 12 or 15 lead EKG can safely rule out an acute myocardial infarction
    True
    False
6. Isolated 3 mm ST segment depressions in II, III, and aVF most likely indicate
    Old lateral wall MI
    Acute Injury of the septal wall
    Diaphragmatic ischemia
7. A frequency response of 0.05 to 100 Hz is "diagnostic quality" for adult patients.
    True
    False
8. The formula ( the S in V1 or V2 plus the R in V5 or V6 if > 30) indicates:
    COPD
    LVH
    LAD
    RVH
9. A gain of ONE means that 1 millivolt of energy will move the tracing 1 mm.
    True
    False
10. The Lead used to identify, and discriminate between Right and Left BBB?
    V1
    II
    I
Base the next two questions on this 12 Lead EKG


11. The EKG above shows?

    Acute DMI
    Inferior wall ischamia
    Acute Anteroseptal-lateral MI
12. ST depressions in the above 12 lead EKG can be referred to as:
    ischemic
    scar
    reciprocal
