Sample Question 1
What are the potential causes of wide complex tachycardia?

Ventricular fibrillation

VTSVT with pre-existing bundle branch blockSVT with aberrancyWPW (antidromic reciprocating tachycardia)ArtifactPaced rhythm

Atrial flutter

Sinus bradycardia

Sample Question 2
It is useful to look at a baseline EKG in SR when determining the etiology of a WCT. What would you look for in the baseline EKG if the patient had WPW or a preexisting BBB?

Atrial fibrillation; Sinus tachycardia

Prolonged QT interval; Narrow QRS complex

ST segment elevation; T wave inversion

Pre-excitationSimilar BBB (SVT), different BBB (VT)

Sample Question 3
What are some EKG characteristics used to distinguish VT from SVT?

ST segment elevation, peaked T waves, shortened QT intervals

Sinus tachycardia, wide QRS complexes, inverted P waves

VTAV dissociation (P waves marching through, capture, fusion)NW axisPrecordial concordanceLB with QRS >160ms, RB with QRS>140msStructural heart diseaseSVT with aberrancyTypical BBB (especially RBBB with rsR’)

Absent QRS complexes, irregular rhythm, continuous P waves
