Analysis of Factors Related to Return of Spontaneous Circulation in Patients with Out-of-Hospital Cardiac Arrest in Korea: Using Data from the 2019 Acute Cardiac Arrest Survey

This study aimed to analyze the characteristics of out-of-hospital acute cardiac arrest patients collected from the Korea Centers for Disease Control and Prevention to identify the current status and provide basic data to increase the recovery rate of out-hospital acute cardiac arrest patients. As a result of the study, the number of acute cardiac arrest patients in Korea in 2019 was 30,279, of whom 1,505 (64.4%) were men and 10,774 (35.6%) were women. Of the total patients, 1,056 (51.7%) showed good neurological outcomes when paramedics performed defibrillation at the pre-hospital stage (p = 0.001). In the initial review of electrocardiographic rhythm performed by paramedics, 1,025 patients (52.8%) showed ventricular fibrillation and pulseless ventricular tachycardia, which indicated good neurological outcomes (p = 0.001).
