Four patients with chest pain and ‘normal’ ECG: can you trust the computer interpretation?

Dr. Smith's ECG Blog

4,5] We have now formally studied this question: Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review.[6] Other signs of OMI that complement the ECG include new regional wall motion abnormalities and refractory ischemia References 1.

Physical Examination as a Helpful Aid in Decision-Making in Challenging ECGs

Dr. Smith's ECG Blog

An initial electrocardiogram (ECG) is provided below. Learning Point: Concordant ST segment elevation can arise from profound ischemia triggered by ventricular tachycardia (VT), or it may represent an exaggerated basal ST change accompanying tachycardia. The patient was promptly admitted to the hospital for further evaluation.

Hypertrophic Cardiomyopathy

EMS 12-Lead

There is broad subendocardial ischemia as demonstrated by STE aVR with concomitant STD that almost appears appropriately maximal in Leads II and V5. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. This is the initial ECG: The QRS is widened with a regular cadence, and there are no discernable P waves.

Profound ST Elevation in V1-V3. What do you think?

A Deep Neural Network learning algorithm outperforms a conventional algorithm for emergency department electrocardiogram interpretation. JACC 69(23):1694-1703; April 4, 2017. I do research on Cardiologs' algorithm: Smith SW et al. Cardiologs founder, Yann Flereau, was named by MIT as the European Innovator of the Year. What an honor.
