Having a defibrillator close at hand can make the difference between life and death for someone experiencing life-threatening arrhythmia. The medical device administers an electric shock to essentially restart one’s heart rhythm when it goes off the rails, thus preventing cardiac arrest and potentially saving that person’s life. There are multiple types of defibrillators out there, but the one we’ll focus on today is called an automated external defibrillator (AED).
