An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
A defibrillation device that is often available outside of medical centers is the automated external defibrillator (AED), [8] a portable machine that can be used with no previous training. That is possible because the machine produces pre-recorded voice instructions that guide the user.
A wearable cardioverter defibrillator (WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care. It is a leased device.
In 1972 Bernard Lown, the inventor of the external defibrillator, and Paul Axelrod stated in the journal Circulation – "The very rare patient who has frequent bouts of ventricular fibrillation is best treated in a coronary care unit and is better served by an effective anti-arrhythmic program or surgical correction of inadequate coronary ...
Defibrillation. Defibrillation: position of the electrodes of a defibrillator on the human body. The standard defibrillation device, prepared for a fast use out of the medical centres, is the automated external defibrillator (AED), a portable machine of small size (similar to a briefcase) that can be used by any user with no previous training.
Prior studies suggest that biphasic shock is more likely to produce successful defibrillation after a single shock, however rate of survival is comparable between the methods. [102] In out-of-hospital arrests, the defibrillation is made by an automated external defibrillator (AED), a portable machine that can be used by any user. The AED ...
