What is the purpose of a defibrillator?
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.
Does a defibrillator help the heart?
Because it has a pacemaker built into it, a defibrillator also has the capability of stimulating the heart like a pacemaker, to help stop fast rhythms, at times, and to prevent the heart from getting too slow.
What does it mean when a defibrillator shocks your heart?
If it detects a life-threatening rapid heart rhythm, it tries to slow the rhythm to get it back to normal. If the dangerous rhythm does not stop, the ICD sends an electric shock to the heart to restore a normal rhythm. The device then goes back to its watchful mode.
What is the device that shocks the heart?
An implantable cardiac defibrillator (ICD) is an electronic device that is placed inside the body. An ICD constantly keeps track of your heart rhythm and sends a small shock to the heart muscle if the rhythm becomes abnormal (arrhythmia). If a shock is needed, it can be very uncomfortable, but it is over very quickly.
What kind of shock does a defibrillator give?
The implantable cardioverter defibrillator picks up a heart condition, called cardiac arrhythmias immediately and delivers an automatic small shock to restore a normal heartbeat. Patients often describe the shock as a sensation that one can associate with a swift kick to the chest.
When does a defibrillator need to be used?
A defibrillator is a device that uses electricity to re-start the heart or shock it back into its correct rhythm. It is used when someone has a sudden cardiac arrest (SCA). This is when the heart suddenly stops pumping. The defibrillator analyses the heart rhythm and decides whether an electric shock is needed.
How does an implanted heart defibrillator work?
An ICD (implantable cardioverter defibrillator) is a small device that is placed in the chest. It helps to keep the heart beating normally. If the heart beats too fast, the device sends a powerful shock to the heart to help it beat normally again. For many people with heart disease,…
What do pacemakers and defibrillators do for You?
Pacemakers and defibrillators, or implantable cardioverter defibrillators (ICDs), are mechanical treatments that give electrical shocks to the heart to restore regular rhythm to patients with arrythmias (irregular heartbeats). An ICD is used to detect and suppress the presence of heart arrhythmias.

How is a defibrillator used to treat fibrillation?
An ECG showing ventricular fibrillation – a condition when the heart quivers, rather than pumps, due to disorganized electrical activity in the ventricles of the heart. (Photo Credit : Jer5150 / Wikimedia Commons) Defibrillation is carried out with the help of a device called a defibrillator.
