A driver who suffered a heart attack and crashed into a guardrail was saved by a defibrillator salesman and two nurses who happened to be passing by.

The salesman, Steve Earle, was transporting an automated external defibrillator, a device used to shock the heart into a normal rhythm.

"When I saw what was happening, I jumped out and instinctively grabbed the AED, just in case," Earle told KSDK-TV of St. Louis.

Two nurses who also stopped when they saw the wreck Friday evening began performing CPR on the driver, Carolyn Holt. The defibrillator restored her pulse, and Holt was recovering in a hospital this week.

"Two RNs, a man that was able to get her out of the vehicle, the man with the AED — that just doesn't happen," said Mary Blome, one of the nurses.
