Differences among young unwitnessed sudden cardiac death, according to time from last seen alive: Insights from a 15-year nationwide study
Authors' conclusion
The majority of unwitnessed SCD subjects had not been seen alive within 1 hour of being found dead. Clinical- and autopsy-related characteristics differed between the 2 groups.
Study context
