How are defibrillators used in the body?

ICD: Icds are implanted to monitor the electrical activity of very abnormal hearts to see if a life threatening rhythm occurs. If it detects one of these rhythms, it will charge its capacitor and fire a shock to defibrillate the heart back to stable rhythm. In appropriate patients these devices save lives. ...Read more

One is a vest worn on the outside that functions like the internal; this isn't for long term use. Then there is the AED automatic external defibrillator for lay people to use and the external defibrillators for medical staff. ...Read more

Do defibrillators work?

Oh yes: Defibrillators are extraordinarily effective devices for the treatment of what would otherwise be fatal lower chamber heart rhythms. That said, they must be used in an extremely timely fashion or their benefits will not prevent irreversible damage from the lack of blood flow seen in these dangerous rhythms. ...Read more

What types of defibrillators are there?

Internal & external: Implantable (internal) defibrillators remain in the body, whereas external defibrillators are the boxes with paddles that you see on tv shows. They both shock the heart out of life-threatening cardiac arrest rhythm if need be. There are automated external units that lay people can use; you put paddles on person's chest and the machine determines the rhythm and speaks commands to give a shock. ...Read more

What is a defibrillator?

Multiple types: External defibrillators are used on an emergency basis to convert life threatening rapid ventricular arrhythmias. These are also available in a wearable form called a life vest. There are also implantable defibrillators inserted in survivors of sudden death or those at risk of sudden death. ...Read more

Why would a defibrillator not work?

Debirillator: A defibrillator is an electric device and subject to all the failure modes of any electric device. Assuming the device has a good power source and all components are working and it delivers the shock appropriately, there is no guarantee the heart will respond. If the cardiac status is too far gone electrophysiologically the rhythm won't convert. ...Read more
