an apparatus used to produce defibrillation by application of brief electroshock to the heart, directly or through electrodes placed on the chest wall.
automatic external defibrillator (AED) a portable defibrillator designed to be automated such that it can be used by persons without substantial medical training who are responding to a cardiac emergency.
automatic implantable cardioverter-defibrillator (AICD) (implantable cardioverter-defibrillator (ICD)) an implantable device that detects sustained ventricular tachycardia or fibrillation and terminates it by a shock or shocks delivered directly to the myocardium, thus preventing sudden cardiac death. Three different types of electrodes may be used: a superior vena cava spring lead, a transvenous bipolar electrode, and a ventricular patch lead. One third of the patients who have had this device implanted have received spontaneous device countershocks. Other reported side effects are similar to those of pacemakers.

Patient discussion about defibrillator
Q. Does anyone know if its possible to get breast implants if i have an implanted defibrillator? I have hypertrophic cardiomyopathy. I'm 27 and in great health, I workout 6 days a week and I have no further symptoms.
A. Thanks for your help. In fact I have an appointment with my cardiologist in a couple of weeks and if he says its OOK I will definitely consult it with the plastic surgeon as well. However I always try to do some additional research on my own and get second opinions.More discussions about defibrillator
