LOS ANGELES–Finally, a reason to have lived through the 70s -- and another fine reason to relive one of disco's most enduring triumphs, the 1977 hit by the Brothers Gibb, "Stayin' Alive": it could save someone's life.

In performing Cardiopulmonary Resuscitation -- CPR -- the perfect rhythm is 100 compressions per minute, and done properly, it can triple a heart arrest victim's chances of survival. But how, when you're saving a life, do you achieve that ideal rhythm of life-saving compressions? Think "Stayin' Alive."

Medical students and physicians trained to perform CPR to the bouncing beat of "Stayin' Alive" maintained close to the ideal rhythm recommended by the American Heart Association for chest compressions during CPR, according to a study to be presented Oct. 27 at a Scientific Assembly of the American College of Emergency Physician's annual meeting.
