Defibrillators are devices that restore a normal heartbeat by sending an electric pulse or shock to the heart. They are used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart's beating if the heart suddenly stops.
What happens during defibrillation?
Defibrillation delivers an electrical shock that causes all the heart cells to contract at the same time. This stops the abnormal rhythm and allows the heart to restart normal electrical activity.
What's the purpose of a defibrillation?
The ICD responds to irregular life-threatening heart rhythms from the lower chambers of the heart with pacing that corrects a fast rhythm and promotes a normal heartbeat, or a shock (defibrillation) that resets the heart rhythm to prevent sudden cardiac arrest.
