Workout Quiz
7 questions. Answers are graded instantly with expert explanations.
1. Which ECG finding is part of the Aslanger pattern?
ST elevation in all three inferior leads
ST elevation in lead III but not the other inferior leads
Diffuse PR depression
Coved ST elevation in V1–V2 only
2. Which additional ECG feature supports the Aslanger pattern?
ST elevation in V2 greater than V1
ST elevation in V1 greater than V2
Long QT interval
Diffuse T-wave flattening
3. Which coronary occlusions are most associated with the Aslanger pattern?
Proximal LAD only
Left circumflex or right coronary artery
Left main only
Septal perforator only
4. What is T wave alternans?
Hyperacute T waves from LAD occlusion
Alternating QRS amplitude from pericardial effusion
T wave inversion in V1–V3
Beat-to-beat variation in T wave amplitude or morphology
5. Why is T wave alternans clinically important?
It strongly suggests impending torsades de pointes
It is a benign normal variant
It is diagnostic of pericardial tamponade
It rules out QT prolongation
6. Which statement about Barcelona criteria in LBBB is correct?
They are identical to modified Sgarbossa criteria
They require ST elevation in two contiguous inferior leads
Concordant ST depression can be considered abnormal in any lead
They ignore QRS amplitude
7. Using the Barcelona criteria, which finding is considered positive?
Any ST elevation in LBBB regardless of QRS size
ST deviation ≥1 mm opposite the QRS direction when the QRS complex is ≤6 mm
ST elevation only if it is >50% of the S-wave depth
Isolated T-wave inversion in aVL
