Wide-complex tachycardia

Assume any wide-complex tachycardia is ventricular tachycardia until proven otherwise (it is safer to incorrectly assume a ventricular dysrhythmia than supraventricular tachycardia with abberancy)

Regular
- Monomorphic ventricular tachycardia
- PSVT with aberrant conduction:
  - PSVT with bundle branch block^
  - PSVT with accessory pathway
  - Atrial flutter with bundle branch block^
- Sinus tachycardia with bundle branch block^
- Accelerated idioventricular rhythm (consider if less than or ~120 bpm)
- Metabolic
  - Hyperkalemia
  - Digoxin toxicity
  - Severe metabolic acidosis
Irregular
- Atrial fibrillation/atrial flutter with variable AV conduction AND bundle branch block^
- Atrial fibrillation/atrial flutter with variable AV conduction AND accessory pathway (e.g. WPW)
- Atrial fibrillation + hyperkalemia
- Polymorphic ventricular tachycardia
  - Torsades de pointes
  - Nonsustained ventricular tachycardia

^Fixed or rate-related
