Defibrillaatio
Defibrillaatio is a medical procedure that delivers a controlled electric shock to the heart to terminate life-threatening arrhythmias and restore a normal rhythm. It is typically used for shockable rhythms such as ventricular fibrillation and pulseless ventricular tachycardia. It is not indicated for asystole or pulseless electrical activity without other measures.
Defibrillation can be delivered externally or internally. External defibrillation uses automated external defibrillators (AEDs) or manual
In practice, defibrillation is part of the chain of survival for cardiac arrest: early recognition, prompt CPR,
Energy levels vary by device and rhythm; typical external shocks use biphasic energy in the range of
