Heart’s Electrical System
continued
• Ventricular fibrillation common abnormal heart rhythm
after heart attack, electrocution, hypothermia and
other causes
- Ventricles of heart are quivering instead of beating
rhythmically
- In about ½ of cases of cardiac arrest, victim’s heart is in
fibrillation

How AEDs Work
• Automatically checks
victim’s heart rhythm to
detect fibrillation
• Advises whether victim
needs a shock
- The shock (defibrillation)
is an attempt to return
heart to a more normal
rhythm

AED Use in Children
• Use pediatric pads
