Figure 10. Algorithm summarizes diagnostic and therapeutic clinical management for survivor of ventricular fibrillation cardiac arrest. Unless cardiac arrest is caused by acute myocardial infarction (MI) or is the result of a treatable condition (eg, Wolff-Parkinson-White (WPW) syndrome, ischemia, drug-induced proarrhythmia), recommended therapy is an implantable cardioverter-defibrillator (ICD).
