The diagnostic accuracy of a shock advisory algorithm in automated external defibrillators in the presence of real-world artifacts
Authors' conclusion
The performance of this shock advisory algorithm during real-world resuscitations with or without artifacts, exceeded AHA recommendations and the requirements in international standards.
