How does a defibrillator function?
A defibrillator brings the cells of the heart back into a unified and timed contraction by introducing a electrical charge ( measured in joules which are equivalent to a one-amp-second of amplitude).
What happens after defibrillator is applied?
When used with a heart attack patient who is suffering form arrhythmia or who's heart has stopped completely. The defibrillator causes the muscles of the heart contract, (hopefully) and to return to its normal rhythmic pattern.
Externally shocks the heart to restore a normal cardiac rhythm?
A defibrillator device can accomlish this.
What do defibrillator do to the heart pump?
'shock' the irregular rythme hopefully back into a normal one
What can you do or not do with a defibrillator?
A defibrillator is used when the heart goes into an abnormal rhythm called Ventricular Fibrillation. A normal heart will have a certain rhythm. The upper chambers of the heart, known as the Atria. One chamber is called the Atrium. The lower chambers are the ventricles. Each chamber is connected by valves in the heart. The right side of the heart receives oxygen poor blood. It is pumped out to the lungs and oxygen rich blood is pumped out by the left side of the heart. The heart has it's electrical system which keeps it in rhythm. The atrioventricular node is the heart's pacemaker and controls the rhythm of the heart. During a cardiac arrest the lower chambers or the ventricles can begin to quiver. They are unable to pump oxygenated blood into the body. Most importantly they can pump blood to the brain. If this is not corrected quickly a person will die. A defibrillator will deliver a shock of electricity to the heart in order to stop the quivering of the ventricles and stablize the rhythm of the heart. When using a defibrillator you usually start with a lower shock and increase the strength of the shock if it is not working and fibrillation is not correcting itself. Basically it restarts the heart to return it to a normal sinus rhythm. A defibrillator cannot bring someone back to life if the heart has completely stopped for a period of time. Sometimes a defibrillator doesn't work because there is too much damage to the ventricles. An inferior wall M.I. is a heart attack that occurs at the back of the heart and usually destroys the ventricle. A defibrillator cannot correct this. Defibrillators can also be used if someone is experiencing Atrial Fibrillation. Generally the process is the same but the patient may be conscious. Atrial Fibrillation is not as serious as Ventricular Fibrillation but if it is not corrected the patient can develop blood clots or other complications.
Can a defibrillator process?
No, because a defibrillator has no processor in it. All that a defibrillator does is run electricity through your heart to get it started. Now the machines that monitor your heart, they have processors, but not a defibrillator.
Why would and implanted defibrillator vibrate?
Why would and implanted defibrillator in your heart vibrate

What machine is used when someone's heart stops?
defibrillator
Do doctors use a defibrillator?
Answer yes, in heart surgery

How do modern defibrillators work?
For example, a ‘shock’ circuit used in a defibrillator has three key components: a high voltage source, a capacitor and switches. The charges pulse the heart, pumping blood.
What are the names of two devices that are inserted into the body to electrically shock the heart into regular rhythm?
Pacemaker Defibrillator
A machine that starts your heart rate again when it stopswhat is it called?
A defibrillator.
After defibrillator implant what happens if heart speeds up quickly?
it shocks it
Why would a defibrillator be implanted?
Paramedics and EMTs use a defibrillator to stop the heart. They are used primarily when a patient is in ventricular fibrillation. A shock is administered to stop the heart in the hopes that the heart's natural pacemaker, the sinus node, will take over and put the patient back into a normal sinus rhythm.
What is the use for an automated external defibrillator?
it can start your heart back beating again; especially good for a heart attack
