Key result
Cellular video-phone assisted interpretation of prehospital ECGs showed high interphysician reliability for detecting ST-segment elevation (ICC 0.98), similar to printed ECG interpretation (ICC 0.99).
Why the study?
Does real-time cellular video-phone transmission of prehospital ECGs provide similar interphysician reliability compared to printed ECGs among physicians evaluating STEMI?

Does real-time cellular video-phone transmission of prehospital ECGs provide similar interphysician reliability compared to printed ECGs among physicians evaluating STEMI?
Absolute Event Rate: 0.98% vs 0.99%
Cellular video-phone transmission of prehospital ECGs is a highly reliable alternative to printed ECGs for identifying STEMI, which may facilitate earlier triage and reperfusion.
González et al. (2011) conducted an observational in Acute ST-segment elevation myocardial infarction (STEMI) (n=27). Cellular video-phone (VP) assisted interpretation of ECG vs. Printed ECG interpretation was evaluated on Interphysician reliability for presence of ST-segment elevation (intraclass correlation coefficient) (95% CI 0.96-1). Cellular video-phone assisted interpretation of prehospital ECGs showed high interphysician reliability for detecting ST-segment elevation (ICC 0.98), similar to printed ECG interpretation (ICC 0.99).
