Association Between No-Flow Time, Prehospital Low-Flow Time, and Conversion to Nonshockable Rhythm in Patients With Out-of-Hospital Cardiac Arrest Presenting With Initial Shockable Rhythm: A Nationwide Prospective Study in Japan.

ABSTRACT:

Background

Out-of-hospital cardiac arrest (OHCA) with initial shockable rhythm generally has a favorable prognosis. However, the prognosis worsens when this rhythm transitions to nonshockable rhythm on hospital arrival. This study aimed to investigate the association between no-flow time (NFT), prehospital low-flow time (LFT), and the conversion to nonshockable rhythm on hospital arrival in patients with OHCA initially exhibiting shockable rhythm.

Methods

We analyzed adult patients with OHCA from the JAAM-OHCA (Japanese Association for Acute Medicine Out-of-Hospital Cardiac Arrest) registry (June 2014-December 2020) with initial shockable rhythm. The primary outcome was rhythm conversion to nonshockable on hospital arrival. Adjusted odds ratios (aORs) with 95% CIs were calcu
