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