The human heart is a delicate muscle and must be taken care of. Sometimes disease can cause malfunction to occur and the heart to stop beating. When this happens, it is necessary to resuscitate the person to bring him/her back to life. This is done by sending electric shocks to the heart muscle until it starts beating again. This shock is administered by a device called a defibrillator. These defibrillators range in the amount of shocks they can administer. From the discrepancies in the research, there does not seem to be an universal amount that will revive a heart.
