All ECG 74

  1. Atrial fibrillation with a rapid ventricular response
  2. Left bundle branch block

This ECG is considered "SVT with aberrancy" due to the atrial fibrillation with a fast ventricular rate and a wide QRS complex in the pattern of a left bundle branch block. The Brugada criteria can be used to verify that this wide complex tachycardia (WCT) is NOT ventricular tachycardia. In a small percentage of cases, ventricular tachycardia can be irregularly irregular, thus this finding does not completely exclude ventricular tachycardia on this ECG.
