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