The accuracy of EKG diagnosis following cardiac arrest and return of spontaneous circulation (ROSC), particularly when determining the need to activate the Cath lab during the middle of the night, can be highly challenging. Baldi et al. published this study regarding “Association of Timing of Electrocardiogram Acquisition After Return of Spontaneous Circulation With Coronary Angiography Findings in Patients With Out-of-Hospital Cardiac Arrest”. They found that performing an EKG 8 minutes post-ROSC improves the accuracy of EKG interpretation.
