WASHINGTON - U.S. doctors have found the Bee Gees 1977 disco anthem "Stayin' Alive" provides an ideal beat to follow while performing chest compressions as part of CPR on a heart attack victim.

The American Heart Association calls for chest compressions to be given at a rate of 100 per minute in cardiopulmonary resuscitation (CPR). "Stayin' Alive" almost perfectly matches that, with 103 beats per minute.

CPR is a lifesaving technique involving chest compressions alone or with mouth-to-mouth rescue breathing. It is used in emergencies such as cardiac arrest in which a person's breathing or heartbeat has stopped.
