Podcast 806: Normal ECGs

Podcast 806: Normal ECGs

Contributor: Jared Scott, MD

Educational Pearls:

  • Physicians are typically advised not to trust computer interpretation of ECGs
  • Retrospective study was done of computer interpreted normal ECGs to evaluate the accuracy of such an interpretation
    • 989 ECGs were interpreted as "Normal sinus rhythm, Normal ECG" by proprietary cardiology software on MUSE Cardiology Information System
    • These EKGs received follow up interpretation by cardiologists which was considered the "gold standard" for interpretation
    • 18.6% of "normal ECG" had at least one abnormality identified by the cardiologist
      • 6.1% of these discrepant interpretations were deemed potentially clinically significant
      • Only 1% were classified as possible ischemia
    • On retrospective chart review:
      • Six patients underwent non-emergent cardiac catheterization
      • Two had cardiac interventions
        • One had three PCI stents to a prior CABG graft
        • One had a scheduled outpatient cardiac catheterization but was admitted and ended up receiving a CABG graft
  • Study showed that discrepancies between computer interpretation of "Normal ECG" and cardiologist re-interpretation were not clinically significant
  • Emergency physicians should still screen ECGs per AHA guidelines
