Answer

In patients with suspected RBBB, also consider the following in the differential diagnosis:

  • Interventricular conduction delay

  • Right bundle branch aberrancy (premature atrial contractions, supraventricular tachycardia)

  • Premature ventricular contractions and other ventricular arrhythmia

  • Paced ventricular beat

  • Wolff-Parkinson-White syndrome (ventricular preexcitation)

  • Brugada syndrome

  • Arrhythmogenic right ventricle cardiomyopathy (ARVC)
