Wide Regular Tachycardia[1]

Wide Regular Tachycardia (consistent with ventricular tachycardia).

Pulseless: see Adult pulseless arrest

  • Unstable: Hypotension, altered mental status, shock, ischemic chest discomfort, acute heart failure
  • Stable:
  • Medications
    • Procainamide (first-line drug of choice)
      • 20-50 mg/min until arrhythmia suppressed (max 17mg/kg or 1 gram); then, maintenance infusion of 1-4mg/min x 6hr
        • Alternative administration: 100 mg q5min at max rate of 25-50 mg/min[2]
      • Stop if QRS duration increases >50% or hypotension
      • Avoid if prolonged QT or CHF
      • Favored over Amiodarone in PROCAMIO trial; termination of tachycardia in 67% of procainamide group vs 38% of amiodarone group, adverse cardiac events 9% vs 41%, respectively [3]
    • Amiodarone (agent of choice in setting of AMI or LV dysfunction)
      • 150 mg over 10min (15 mg/min), followed by 1 mg/min drip over 6hrs (360 mg total)[4]
      • Then 0.5 mg/min drip over next 18 hrs (540 mg total)
      • Oral dosage after IV infusion is 400 -800 mg PO daily
    • Consider adenosine
    • Synchronized cardioversion (100J)
