Quick Summary

An automated external defibrillator (AED) is a portable medical device used in emergency situations to treat cardiac arrest by administering electric shocks to reset a normal heart rhythm. AEDs are designed for use by the general public, even without prior training, and are often found in public places like airports. Immediate use of an AED is crucial for successful restoration of heart rhythm during cardiac arrest. The development of AEDs built upon earlier research into defibrillation techniques, with modern devices delivering shocks in a biphasic waveform for improved safety and effectiveness.1
