This is secondary analysis of a paper recently reviewed, which analysed the change in ECG morphology following ROSC from out-of-hospital Cardiac Arrest.
The Study
Naas, CJ et al. Associations with resolution of ST-segment elevation myocardial infarction criteria on out-of-hospital 12-lead electrocardiograms following resuscitation from cardiac arrest. Resuscitation, Volume 209, 110567.
What They Did
This was a secondary analysis of the original paper(1), which found that a significant number of ECGs changed morphology from a STEMI, post resuscitation in the out of hospital environment to a NSTEMI, on arrival to hospital. This study aimed to identify treatments, cardiac arrest characteristics, and time factors associated with this ECG change.
Characteristics of the arrests, “times, and treatments were analyzed for association with change in ECG classification between the Out-of-Hospital(OOH)” and Emergency Department (ED).
