Indicators for placing ICDs in children

Class I:

  1. Cardiac arrest due to ventricular fibrillation (VF) or VT that is not temporary or reversible.
  2. Spontaneous sustained VT.
  3. Syncope of undetermined origin with clinically relevant, hemodynamically significant sustained VT or VF induced at electrophysiological study when drug therapy is ineffective, not tolerated, or not preferred.
Class IIa: None.

Class IIb:
  1. Cardiac arrest presumed to be due to VF when electrophysiological testing is precluded by other medical conditions.
  2. Severe symptoms attributable to sustained ventricular tachyarrhythmias while awaiting cardiac transplantation.
  3. Familial or inherited conditions with a high risk for life-threatening ventricular tachyarrhythmias such as long QT syndrome or hypertrophic cardiomyopathy.
  4. Recurrent syncope of undetermined etiology in the presence of ventricular dysfunction and inducible ventricular arrhythmias at electrophysiological study when other causes of syncope have been excluded.
