Background and Identification
A defibrillator is a medical device used to treat potentially fatal arrhythmia (irregular heartbeat) by transferring electric currents to the heart.
There are a few different types of defibrillators:
- Automated External Defibrillator (AED)—Can be used by untrained bystanders in emergencies
- Implantable Cardioverter Defibrillator (ICD)—Surgically implanted inside a patient’s body to treat potentially fatal cardiac arrhythmias
- Wearable Cardioverter Defibrillator (WCD)—Portable devices that rests outside a patient’s body
