We examined the prognostic information that postresuscitation ECG rhythm can provide for predicting outcome in OHCA survivors. Methods: The retrospective observational study enrolled 56 successfully resuscitated nontraumatic adult OHCA patients. Postresuscitation 12-lead ECGs of the enrolled patients were interpreted independently by two cardiologists. We compared baseline clinical characteristics, CPR process, and outcome in the 8 patients with postresuscitation accelerated idioventricular rhythm (AIVR, n = 8) and the 48 without AIVR. Results: The AIVR group had a higher proportion of patients with coronary artery disease (50% vs. 15%), initial ventricular tachycardia/ fibrillation rhythm (50% vs. 8%), and cardiac origin of OHCA (75% vs. 23%). AIVR patients had longer total CPR duration (32 vs. 18 min) and higher dose of epinephrine use (10 vs. 3 mg). Postresuscitation AIVR was associated with an increased incidence of repeated CPR within 1 h after return of spontaneous circulation (38% vs. 4%), and lower 7-day survival rate (0% vs. 50%). Conclusions: AIVR on postresuscitation ECG offers a prognostic factor related to a higher repeated CPR rate within 1 h after return of spontaneous circulation and a lower 7-day survival rates in successfully resuscitated OHCA victims. ? 2007 Springer-Verlag.[SDGs]SDG3adrenalin; aged; article; cardiologist; circulation; controlled study; coronary artery disease; drug megadose; electrocardiogram; female; heart arrest; heart rhythm; heart ventricle fibrillation; heart ventricle tachycardia; human; major clinical study; male; observational study; outcome assessment; outpatient; prognosis; resuscitation; retrospective study; survival rate; survivor; Accelerated Idioventricular Rhythm; Aged; Aged, 80 and over; Cardiopulmonary Resuscitation; Coronary Artery Disease; Electrocardiography; Epinephrine; Female; Heart Arrest; Humans; Male; Middle Aged; Prognosis; Retreatment; Retrospective Studies; Survival Analysis; Survivors; Tachycardia, Ventricular; Time Factors; Vasoconstrictor Agentsjournal article10.1007/s00134-007-0633-z174575732-s2.0-34548159492
