BOB DOUGHTY: If the heart does not start beating, continue with chest compressions until help arrives. For a choking victim who is unconscious with no heartbeat, clear the airway first. Then do chest compressions.
Dr. Sayre suggests that medical workers do both the breathing method and chest compressions. He says some victims, including babies, need the mouth-to-mouth breathing with the compressions. Still, the doctor says it is better to do just chest compressions than to do nothing. CPR is not difficult to learn. Many organizations teach it.

PAT BODNAR: Most CPR training now includes how to use an automated external defibrillator, or AED. Defibrillators use electric shocks to correct abnormal heartbeats that can lead to sudden death. Such devices are found increasingly in public places like airports, restaurants and office buildings. A recorded voice on the AED guides the user. The voice provides detailed information about what to do.
The defibrillator of today has developed from the first defibrillators. Medical historians say the devices appeared late in the nineteenth century.
BOB DOUGHTY: In the nineteen twenties, American Claude Beck performed the first surgical operations to repair damaged hearts. Dr. Beck worked at what is now called Case Western Reserve University School of Medicine in Ohio.
Another doctor, Carl J. Wiggers, had kept laboratory animals with heart stoppage alive by massaging their hearts. Then he followed this rubbing with electrical defibrillation. This led Claude Beck in his efforts to help return normal heart actions to human patients.
