Out-of-Hospital Cardiac Arrest 30-Day-Outcomes: The Importance of the First Electrocardiogram After Successful Resuscitation.

Background: While there is substantial evidence on the impact of prehospital resuscitation efforts on survival after out-of-hospital cardiac arrest (OHCA), the importance of the first electrocardiogram after return of spontaneous circulation has been much less studied.

Objectives: The aim of this study was to identify prognostically relevant electrocardiographic findings in patients after OHCA due to myocardial infarction (MI).

Methods: A total of 119 patients admitted to hospital after suffering an OHCA due to MI were retrospectively analyzed.
