An implantable cardioverter-defibrillator (ICD) is indicated in:
Patients who survive sudden death and symptomatic patients
Patients with a family history of sudden cardiac death
Generally accepted criteria for implantation of an<unk>  also include:
Inducibility on electrophysiologic testing
Positive genetic test, although a negative result does not exclude the presence of a previously unreported mutation or the occurrence of a future arrhythmic event
Inappropriate shocks may be delivered due to:
The occurence of tachycardias such as sinus tachycardia and atrial fibrillation.
Oversensing of the tall, narrow peaked T wave
Short QT syndrome AICD placement
Pulseless ventricular tachycardia interventions
Wolff-Parkinson-White syndrome cardioversion
Atrial fibrillation cardioversion
Catecholaminergic polymorphic ventricular tachycardia implantable cardioverter-defibrillator
AVNRT vagal maneuvers
Noncompaction cardiomyopathy holter monitoring
Pulseless ventricular tachycardia medical therapy
