Purpose of the Study:
To investigate the impact of initial recorded rhythm on survival after out-of-hospital cardiac arrest (OHCA) in the greater area of Thessaloniki, the second largest city in Greece.
Materials and Methods:
2194 OHCA patients were included in the study. All patients were managed by EMS personnel according to ERC Guidelines and Utstein-style template was used for data reporting. Management and outcome were analyzed and correlated with the initial recorded rhythm (IRR).
Results:
Results are depicted on the Table.

ROSC and survival to hospital discharge after OHCA were significantly higher in patients with a shockable initial rhythm (SIR) (ROSC: 50.5% versus 29.0%, Survival to hospital discharge: 20.1% versus 5.2%). The findings of our study support previous literarute reports that IRR is one of the most important predictors of survival after OHCA.
