Cardiac arrest 175 J defibrillation shocks were not clearly better than 320 J. Level of evidence 2b- Expiry Date October 2003 Cardiac arrest post-arrest: implantable defibrillators reduced mortality. Level of evidence 1b Expiry Date October 2003 Cardiac arrest the polarity of external defibrillator electrode had no clear effect on the success of resuscitation. Level of evidence 1b Expiry Date October 2003 Cardiac arrest automatic defibrillators were less effective than manual Level of evidence 2b Expiry Date October 2003 Cardiac arrest implantable cardioverter defibrillators were not clearly more effective than amiodarone. Level of evidence 1b Expiry Date October 2004 Cardiac arrest High-energy shocks were not clearly better than low-energy shocks. Level of evidence 2b- Expiry Date October 2003 Cardiac arrest brady-asystolic: no clear role for external pacing Level of evidence 2b- Expiry Date November 2003 Cardiac arrest defibrillation: apex-anterior chest pads were probably as effective as apex-posterior pads Level of evidence 4 Expiry Date October 2003 Tachycardia defibrillators implanted with endocardial leads decreased mortality. Level of evidence 2b Expiry Date October 2004 Tachycardia Implantable cardioverter defibrillators clearly decreased mortality. Level of evidence 1b Expiry Date August 2004 Tachycardia implanted defibrillators decreased death. Level of evidence 1b Expiry Date August 2004
