A 62-year-old woman whose arrhythmia is noninducible at EP study has depressed LV function without aneurysm. The following is/are true:


  1. If her arrhythmia is ventricular tachycardia, she is not a candidate for an Automatic Implantable Cardiac Defibrillator (AICD) since it only recognizes fibrillation
  2. If an AICD is appropriate, it offers a 50% improvement in mortality compared to drug therapy
  3. Poor ventricular function is a contraindication to AICD implantation
  4. AICD should not be used for patients awaiting cardiac transplantation
  5. AICD can provide antitachycardia pacing as well as defibrillation

b. If an AICD is appropriate, it offers a 50% improvement in mortality compared to drug therapy

e. AICD can provide antitachycardia pacing as well as defibrillation

The AICD is capable of recognizing ventricular tachycardia as well as fibrillation and can provide antitachycardia pacing, low or high-energy defibrillation or some combination. It offers a 50% improvement in mortality with 95% freedom from SCD at 5 years after implantation. Neither poor ventricular function nor pending transplantation are contraindications to AICD implantation.
