8.4: Energy Stored in a Capacitor

In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the heart—called cardiac or
