ACLS: Wide Regular Tachycardia

  • If pulseless: shock (unsynchronized 200J)
  • If unstable: shock (synchronized 100J)
    • Hypotension, altered mental status, shock, ischemic chest discomfort, acute heart failure
  • If stable:
    • Meds
      • Procainamide
        • 20-50mg/min; then maintenance infusion of 1-4mg/min x6hr
        • Treat until arrhythmia suppressed, QRS duration increases >50%, hypotension, Max 17mg/kg or 1 gram
        • Avoid if prolonged QT or CHF
      • Amiodarone
        • 150mg over 10min (repeat as needed); then maintenance infusion of 1mg/min x6hr
      • Adenosine
        • May be considered for diagnosis and treatment only if rhythm is regular and monomorphic
    • Synchronized Cardioversion (100J)
