A rapid ventricular rate of >100bpm may be in the context of a variety of rhythms that are clinically classified as narrow complex tachycardias (QRS duration <120ms) and wide complex tachycardias (QRS duration >120ms).
  • Tachyarrhythmias

  • Regular Narrow Complex Tachycardia

  • Sinus tachycardia
  • Focal atrial tachycardia
  • Atrial flutter
  • AV nodal reentrant tachycardia
  • AV reentrant tachycardia
  • Irregular Narrow Complex Tachycardia

  • Multifocal atrial tachycardia
  • Atrial fibrillation
  • Atrial flutter with variable block
  • Regular Wide Complex Tachycardia

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

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

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