"Presumed cardiac" arrest in children and young adults: A misnomer?
To use a novel methodology to assess the incidence and specific causes of Out-of-Hospital Cardiac Arrest (OHCA) within a young urban cohort. ⋯ In young adults with OHCA, confirmed cardiac causes were responsible in a minority of cases, and they differed in presentation from those with confirmed non- cardiac causes. Establishing rigorous case ascertainment strategies with linkage to multiple data sources will facilitate a more reliable evaluation of the causes of these events.
