Editing Defibrillation (section)

=== Indications ===
Defibrillation is often an important step in [[cardiopulmonary resuscitation]] (CPR).<ref name="CriticalCare" /><ref name="Marenco" /> CPR is an algorithm-based intervention aimed to restore cardiac and pulmonary function.<ref name="CriticalCare" /> Defibrillation is indicated only in certain types of [[cardiac dysrhythmias]], specifically [[ventricular fibrillation]] (VF) and [[ventricular tachycardia#Classification|pulseless ventricular tachycardia]].<ref name="Tintinalli" /><ref name="Kerber" /> If the heart has completely stopped, as in [[asystole]] or [[pulseless electrical activity|pulseless electrical activity (PEA)]], defibrillation is not indicated. Defibrillation is also not indicated if the patient is conscious or has a pulse. Improperly given electrical shocks can cause dangerous dysrhythmias, such as ventricular fibrillation.<ref name="Tintinalli" />
