ECGs administered by paramedics can speed treatment for severe heart attacks
Date:7/20/2012

rrival at the hospital. 25% had a cardiovascular diagnosis after physician evaluation.

The ECGs of 380 patients were evaluated as positive and transmitted. Of this group, physicians suspected 226 cases of STEMI, of which 96.9% were confirmed. The false activation of the catheterization lab occurred in only seven of the 226 cases, and the physician missed the diagnosis in seven cases.

"The high level of false positives is a concern, given the risk of treatment," notes Dr. Ducas. "We do not have a clear guide as to what are acceptable levels of false positives and negatives. However, we have found both in the literature and in our own study that EMS pre-hospital ECG interpretation is fast, reliable, and plays a pivotal role in the care for patients with STEMI."

In an editorial accompanying the articles, Robert C. Welsh, MD, FRCPC, FAHA, FACC, of the Department of Medicine, University of Alberta and the Mazankowski Alberta Heart Institute, Edmonton, Alberta, Canada, says, "Our colleagues describe a program which provides the optimal platform to advance STEMI care in Canada. Although this approach is dependent on a motivated group of physicians willing to invest additional time and energy to deliver enhanced STEMI care, it allows pre-hospital confirmation of diagnosis, individual patient risk stratification, immediate decision regarding the optimal mode of reperfusion, and expansion of optimal systems of care to rural patients."
