A total of 63 cases were analyzed, integrating clinical data at the time of presentation with post-mortem pathological findings to ensure diagnostic accuracy. Results indicate that irreversible cardiac arrest (ICA) constituted the predominant cause of mortality, with non-shockable rhythms accounting for 88.88% of cases - asystole (80.35%) and pulseless electrical activity (19.65%) - while shockable rhythms (ventricular fibrillation and pulseless ventricular tachycardia) were observed in only 11.12% of cases.

These findings highlight the need for improved diagnostic methodologies, optimized resuscitation strategies, and enhanced resource allocation within emergency settings. This study underscores the necessity for systematic mortality documentation, evidence-based intervention protocols, and targeted management strategies to mitigate preventable deaths in the ED.
