Recognition
- • Wide QRS >120 ms
- • Rate >100
- • AV dissociation
- • Capture / fusion beats
Key findings
- • Monomorphic vs polymorphic
- • Concordance across precordial leads
Clinical importance
- • May progress to VF / sudden cardiac death
Management pearls
- • Unstable: synchronised DC
- • Stable monomorphic: amiodarone 300 mg / procainamide
- • Polymorphic: defib + Mg if torsades
- • Treat underlying ischaemia / electrolytes
