Key result
Shockable initial rhythm linked to ~6.1-fold higher odds of resuscitation success vs nonshockable rhythm.
Why the study?
Associations between in-hospital cardiac arrest event characteristics and immediate resuscitation outcomes require careful evaluation, particularly in small hospital samples. This study examined how initial heart rhythm, cardiopulmonary resuscitation duration, and the arrest-to-resuscitation interval relate to recorded resuscitation success.
Are initial shockable heart rhythm, shorter cardiopulmonary resuscitation duration (<10 minutes), and shorter arrest-to-resuscitation interval (<2 minutes) associated with recorded immediate resuscitation success in hospitalized cardiac arrest patients?
Cross-Sectional (n=38)
No
Are initial shockable heart rhythm, shorter cardiopulmonary resuscitation duration (<10 minutes), and shorter arrest-to-resuscitation interval (<2 minutes) associated with recorded immediate resuscitation success in hospitalized cardiac arrest patients?
In a small Indonesian hospital sample, shockable initial rhythm, initiation of CPR within 2 minutes, and CPR duration under 10 minutes were unadjusted factors associated with recorded immediate resuscitation success, highlighting the need for rapid response and standardized Utstein documentation.

Shockable rhythms were associated with higher resuscitation success; hypothesis-generating and requires prospective validation before guiding protocols.
Background: Cardiac arrest requires timely resuscitation, but associations between event characteristics and immediate resuscitation outcomes require careful interpretation, particularly in small hospital samples.Purpose: To examine the associations of initial heart rhythm, cardiopulmonary resuscitation duration, and arrest-to-resuscitation interval with recorded resuscitation success at Elizabeth Hospital Situbondo, Indonesia.Methods: This observational cross-sectional study included 38 patients selected through convenience sampling during February–March 2025. Data were extracted from patient records and resuscitation documentation using an observation sheet. Aggregate contingency-table counts were reanalyzed using Pearson chi-square or two-sided Fisher exact tests, as appropriate. Crude odds ratios and 95% confidence intervals were calculated where estimable.Results: Resuscitation was recorded as successful in 24 patients (63.2%). Success occurred in 15/18 patients with shockable rhythms versus 9/20 with nonshockable rhythms (odds ratio, 6.11; 95% confidence interval, 1.34–27.96; p = 0.014), and in 17/21 receiving resuscitation for <10 minutes versus 7/17 for ≥10 minutes (6.07; 1.42–26.03; p = 0.011). Success occurred in 24/32 patients with an arrest-to-resuscitation interval <2 minutes and 0/6 with an interval ≥2 minutes (Fisher p = 0.001).Conclusion: All three variables were associated with recorded immediate resuscitation success. These findings support attention to timely response and rhythm assessment but do not establish causality, independent predictors, or a duration threshold for stopping resuscitation.

Pinto et al. (2026) conducted a cross-sectional in In-hospital cardiac arrest (n=38). Shockable initial heart rhythm (VF/PVT) vs. Nonshockable initial heart rhythm (Asystole/PEA) was evaluated on Recorded immediate resuscitation success (OR 6.11, 95% CI 1.34-27.96, p=0.014). Shockable initial heart rhythm was associated with higher odds of recorded resuscitation success vs nonshockable rhythm (83.3% vs 45.0%; OR 6.11, 95% CI 1.34-27.96, p=0.014).
