Overview

  • While a regular wide complex tachycardia is concerning for ventricular fibrillation, it is important to distinguish this from other important causes of wide complex tachycardia.
    • Causes of Wide Complex Tachycardia

    • Regular

    • Monomorphic ventricular tachycardia
    • Supraventricular tachycardia with aberrant conduction (bundle branch block)
    • Supraventricular tachycardia with preexcitation (accessory pathway)
    • Pacemaker-mediated tachycardia - atrial tracking or endless loop tachycardia
    • Irregular

    • Polymorphic ventricular tachycardia
    • Atrial fibrillation with aberrant conduction (bundle branch block)
    • Atrial fibrillation with preexcitation (accessory pathway)
    • Other

    • Artefact - due to CPR, shivering, shaking or other movements
