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.

Defibrillators – Uses
It uses an electrical shock
to reset the electrical state
of the heart so that it may
beat to a rhythm controlled
by its own natural
pacemaker cells

Defibrillators– need
It is there to prevent death
from a cardiac arrest.
The device shocks the heart
if it needs to be shocked,
because of a life-threatening
rhythm disturbance from the
lower chambers of the heart.
It can correct this rhythm.

Defibrillators– importance
A defibrillator delivers a dose of
electric current (often called a
counter-shock) to the heart.
Defibrillation is a treatment for life-
threatening cardiac dysrhythmias,
specifically ventricular fibrillation
(VF) and non-perfusing ventricular
tachycardia (VT).
