Implantable cardioverter-defibrillators (ICDs)are indicated for the following conditions:
1)Cardiac arrest caused by pulseless ventricular tachycardia (VT)
2)Spontaneous sustained VT
3)Asystole
4)Pulseless electrical activity
5)Electrophysiologically inducible VT or ventricular fibrillation (VF)not suppressed by class I antiarrhythmics

Question

Quizplus · Accepted Answer

ICDs have been used since the 1980s to cardiovert,to terminate VT,and to provide backup pacing for bradycardia.Implantation of an ICD is indicated for the following conditions:
F1F1F1S1F1F1F10Cardiac arrest caused by pulseless VT or VF not caused by a transient or reversible event
F1F1F1S1F1F1F10Spontaneous sustained VT
F1F1F1S1F1F1F10Syncope of undetermined origin with clinically relevant electrophysiologically inducible sustained VT or VF when drug therapy is ineffective,not tolerated,or not preferred
F1F1F1S1F1F1F10Nonsustained VT in patients with coronary artery disease,before a myocardial infarction,with left ventricular dysfunction,and with electrophysiologically inducible VT or VF not suppressed by class I antiarrhythmics
