US 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.
