Association between cardiac rhythm conversion and neurological outcome among cardiac arrest patients with initial shockable rhythm: a nationwide prospective study in Japan.
Initial cardiac rhythm, particularly shockable rhythm, is a key factor in resuscitation for out-of-hospital cardiac arrest (OHCA) patients. The purpose of this study was to clarify the association between cardiac rhythm conversion and neurologic prognosis in OHCA patients with initial shockable rhythm at the scene. ⋯ Findings showed that the 1-month neurologic outcome in OHCA patients who converted to non-shockable rhythm at hospital arrival was very poor compared with patients who had sustained shockable rhythm. Also, patients with conversion to PEA had better neurologic prognosis than conversion to asystole.
