Multicenter Study Clinical Trial
Performance of a rectilinear biphasic waveform in defibrillation of presenting and recurrent ventricular fibrillation: a prospective multicenter study.
We tested the hypothesis that shock success differs with initial and recurrent episodes of ventricular fibrillation (VF). ⋯ Presenting VF was terminated with one shock in 87.8% of cases. We observed no significant difference in the frequency of shock success between initial versus recurrent VF. VF recurred in the majority of patients and did not adversely affect shock success, ROSC, or survival.
