In a patient with chronic congestive heart failure, right bundle branch block‐shaped QRS complexes occurred in salvos during atrial fibrillation. The site of origin of these complexes could not be determined from the 12‐lead ECG alone. Recording of a His bundle electrogram showed that both intraventricular aberrant conduction and ventricular tachycardia were responsible for salvos having the same QRS complexes in the 12‐lead ECG.
