Question 1 of 10
1. Question
- The Acute Inferior STEMI is commonly accompanied with Right Ventricular STEMI and/or ______ STEMI.
CorrectIncorrect -
Question 2 of 10
2. Question
The _______________ is the guidelines for diagnosing the Acute STEMI in the presence of the LBBB.
CorrectIncorrect -
Question 3 of 10
3. Question
Acute obstruction, thrombosis of the LMCA is rarely seen in the emergency unit because most patients die before arrival to the hospital.
CorrectIncorrect -
Question 4 of 10
4. Question
One criterion for diagnosing the Acute STEMI in the presence of the LBBB is that discordant ST elevation should not exceed ____% of the depth of the preceding S-wave.
CorrectIncorrect -
Question 5 of 10
5. Question
In the WPW syndrome, significantly wide Q-waves are often present especially in leads III and ____. These most often do not represent a myocardial infarction, and in fact are often referred to as a pseudoinfarction pattern.
CorrectIncorrect -
Question 6 of 10
6. Question
You will frequently encounter peaked T-waves in a given tracing. Two common causes are hyperacute Ts and hyperkalemia. To aid in the diagnosis, you should look at the T-wave base with realization of the following:
- Hyperacute Ts are characterized as broad-based
- Hyperkalemic Ts are characterized as ____-based
CorrectIncorrect -
Question 7 of 10
7. Question
All of the following are often STEMI mimics except:
CorrectIncorrect -
Question 8 of 10
8. Question
A 12-lead tracing exhibits diffuse ST-segment elevation concave up. It is more likely to be a benign normal variant (early repolarization) if…
CorrectIncorrect -
Question 9 of 10
9. Question
It is 03:00 hours in the ED. You have been asked to interpret the serial tracings of a patient in the critical care unit. Your analysis reveals only one observed change:
In leads II, III, avF the T-waves are progressively taller, broad-based and the peak is round and smooth.
Conclusion regarding these observations:
CorrectIncorrect -
Question 10 of 10
10. Question
If a cardiogram demonstrates LVH, we should expect to see ST-segment elevations and depressions as follows:
- ST segment elevations Leads V1, V2, V3
- ST segment depressions Leads V4, V5, V6, I, avL
- Q-waves V1, V2
Consequently you must proceed with caution in the present of LVH especially when searching for the Anterolateral STEMI. In order to acknowledge these ST-segment and T-wave changes, we often describe the tracing as “LVH with _________ changes”.
CorrectIncorrect
