To the Editor In the recently published LUCAS in Cardiac Arrest (LINC) randomized trial, cardiopulmonary resuscitation (CPR) with mechanical chest compressions and simultaneous defibrillation provided no significant improvement over classic manual CPR.1 The study protocol implied the delivery of defibrillation during compressions without pausing for rhythm analysis.2 This strategy was intended to eliminate the usual preshock pause to assess rhythm and to optimize the chest compression fraction throughout cardiac resuscitation. Nevertheless, this strategy is a matter of discussion.
