Can’t Miss ECG Findings for the Emergency Medicine Provider


high-risk ECGSudden cardiac death accounts for almost 400,000 deaths per year in the United States, and EM providers must be adept at discerning subtle, high-risk ECG findings. With the advent of triage ECG protocols, one of the most common interruptions in the ED is a request to “sign off” on an ECG. We present a reference of some of the most important high-risk ECG findings, intended to help ED providers systematically screen patients in triage and the waiting room.

Can’t Miss ECG Findings

  1. Did you know that there are now only 2 (not 3) Brugada ECG types?
  2. Did you know that the 2013 ACCF/AHA criteria for ST elevation MI1 are different from the 2012 European Society of Cardiology (ESC)? The latter also stratifies ST elevation cutoffs for men older and younger than 40 years old, and also has more specific recommendations on right sided and posterior leads.2
  3. Have you heard of an epsilon wave?
