A defibrillator monitors a persons heart beat and some of the automatic types called AED's will tell everyone to stand clear and will apply a shock to get the heart pumping again. The reason electricity can kill you, is that it literally makes the heart beat to its frequency for AC power or freezes the heart for DC power. Normally, the nervous system sends electrical pulses to make the heart beat, but if an external power source to the body is more powerful, it will take over. If the heart beats abnormally because of this, the amount of blood pumped by the heart could be diminished, and hence not enough oxygen to the brain via the blood. Its important to note, that even if an electric shock makes the heart beat faster, the chambers may not be able to draw blood in and then expel it in the quantity needed. The heart needs specific conditions to properly provide proper blood flow at a blood pressure that is not too large causing blood vessels to burst, including in the eyes, and not too little blood pressure that the blood can not make it to vital organs including the brain. It is said that current kills, because while lethal current is quantifiable, the voltage to kill a worker, etc. varies based on the persons body resistance. If the worker is wet, sweatty, and clammy, they will have a lower body resistance, so it will take less voltage to produce the current to kill you. Electric has resistive, capacitive, and inductive elements to it, and a thorough understanding of all aspects is needed before you attempt anything with it. Your skin keeps you alive when you handle smaller devices. There is rumored to be a case where a person wanted to measure his internal body resistance, and chose to do so by puncturing each of his hands with the metal tips from an ohmmeter. The metal leads (tips) of an ohmmeter, when the skins resistance is not there to protect you, can likely be lethal. It only takes about 100 milliamps of current to kill you, 10 milliamps to freeze your muscles, and 1 milliamp to feel it. Since current is proportional to the applied voltage divided by the total resistance and impedance due to capacitive and inductive loads, a voltage that is normally not dangerous to handle can suddenly be deadly without the resistance provided by the skin. Since unexpected changes in resistance, inductance, and capacitance can change the potential for current to flow through the body, it is important that you don't take the safety that has been designed into appliances for granted. There are things there that you may not even realize have been designed to protect you.

A Pacemaker uses electrical stimulation to help maintain proper heart rhythm. You've certainly seen the devices on television which use an electric shock to restart a stopped heart. Neither situation involves death, generally considered to be the cessation of brain activity.

It's impossible revive a dead person. You might be thinking of a video game where someone can use a spell or potion to revive someone, but it's impossible in real life. To get rid of your empty feeling of a dead loved one/friend, don't think about them as much and do activites to keep your mind of him/her. Hoped this helped! :P

Electric shock can stop the heart ,but it can also restart it.
However its easer to stop the Heart than restart it . In most cases it doesnot restart depending how long the heart has stopped.
This type of resusitation should be handled only by professional qualified personnel .

Electricity can kill but cannot revive a dead body. But the right electricity can help a sick person.

not really.. but there have been cases when a person considered to be dead has been found alive while his final services are being carried out..

according to me electricity can't relieve a dead person. but it can cure a person who is mentally disabled
