Key result
Initial cardiac rhythm was significantly associated with survival in cardiopulmonary arrest patients, with survival rates being highest for ventricular fibrillation (48.2%) and lowest for asystole (29.9%).
Why the study?
This study aimed to investigate the causes of arrest in patients admitted with cardiopulmonary arrest and the effect of initial cardiac rhythm on patient survival.

Does initial cardiac rhythm affect survival in patients admitted with cardiopulmonary arrest?
Initial cardiac rhythm is significantly associated with survival in cardiopulmonary arrest patients, with shockable rhythms (VF/PVT) having better outcomes than non-shockable rhythms like asystole.
Initial rhythm may inform arrest prognosis; leaves open whether targeted interventions improve survival in observational data.

Şahin et al. (2023) conducted a cohort in Cardiopulmonary arrest (n=1,009). Initial cardiac rhythm (shockable vs. non-shockable) vs. Non-shockable rhythm (asystole/PEA) was evaluated on Survival (clinical outcome) (p=<0.001). Initial cardiac rhythm was significantly associated with survival in cardiopulmonary arrest patients, with survival rates being highest for ventricular fibrillation (48.2%) and lowest for asystole (29.9%).
