Background

Diagnosis

Treatment

  1. Pulseless: Unsynchronized cardioversion 200J
  2. Unstable: Synchronized cardioversion 100-200J
  3. Stable
    1. Regular (tx as presumed V-tach)
      1. Synchronized cardioversion (100 J)
      2. Procainamide (20mg/min)
      3. Amiodarone (150mg over 10min, then 1mg/min gtt x 6hrs)
        1. Agent of choice in setting of AMI or LV dysfunction
      4. Lidocaine 1-1.5mg/kg IV q5min, repeat prn until up to 300mg/hr
    2. Irregular (tx as presumed preexcited A-fib)
      1. Unsynchronized cardioversion (200J)
      2. Procainamide (20mg/min)
      3. Amiodarone (150mg over 10min, then 1mg/min gtt x 6hrs)
      4. Sotalol (100 mg IV over 5 minutes)
    3. Mg 1-2gm IV over 60-90s, then infuse 1-2gm/hr (for Torsades De Pointes)

DDx Regular

  1. V-tach
  2. SVT w/ BBB (fixed or rate related)
  3. SVT w/ accessory pathway
  4. A flutter w/ BBB
  5. Sinus tachycardia with BBB (fixed or rate related)

DDX Irregular

  1. A-fib/flutter w/ variable AV conduction AND BBB (fixed or rate-related)
  2. A-fib/flutter w/ variable AV conduction AND accessory pathway
  3. A-fib + Hyperkalemia
  4. Polymorphic v-tach/torsades

Disposition

  • Admit all pts (even if converted to NSR with adenosine)
