People without formal medical training can be taught to effectively use portable, computerised devices, which detect ventricular fibrillation and deliver electricity to restore a normal heart rhythm in people who have a cardiac arrest, according to two studies in the New England Journal of Medicine (2000;343:1206,1210).

The survival rate rose to 74% for people who were treated within three minutes after collapse.
Another study by Dr R L Page and colleagues at the Southwestern Medical Center at the University of Texas found a 40% survival rate for 15 people who were treated by flight attendants. They also found that AEDs could be effectively used to monitor heart rhythms in people who were not in ventricular
