Regular
- Ventricular tachycardia (80% of cases)
- PSVT with aberrant conduction:
  - PSVT with bundle branch block (fixed or rate related)
  - PSVT with accessory pathway
  - Atrial flutter with bundle branch block
- Sinus tachycardia with bundle branch block (fixed or rate related)
- Accelerated Idioventricular Rhythm (consider if less than or ~120 bpm)
- Metabolic
  - Hyperkalemia
  - Digoxin toxicity
  - Severe metabolic acidosis
Irregular
- A-fib/flutter with variable AV conduction AND bundle branch block (fixed or rate-related)
- A-fib/flutter with variable AV conduction AND accessory pathway (e.g. WPW)
- A-fib + Hyperkalemia
- Polymorphic v-tach/torsades
