The impact of defibrillation current and pad position on return of spontaneous circulation during refractory ventricular fibrillation

ResuscitationPublished Secondary analysis of the DOSE VF randomised trial

Authors' conclusion

AP delivered higher current than AL positioning; however, pad position rather than delivered current was independently associated with ROSC.
