Interesting ECGs

Once a month at this site there will appear a new 12-lead electrocardiogram (ECG). Accompanying the ECG will be a clinical vignette relevant to the tracing and one or two questions for you to answer. The tracings will be classified by their interpretive difficulty:

 

Basic: The ECG represents a basic clinical problem or basic ECG principle. Should be mastered by a graduating medical student.

 

Intermediate: The ECG presents a more challenging or complex problem. Should be able to be mastered by most graduating Family Practice, Medicine or Emergency Medicine residents.

 

Advanced: Presents a complex, subtle or advanced ECG concept. Physicians with a special interest in ECG’s or Cardiology fellows should find these tracings interesting.

 

The Answers and Follow up will be posted after everyone is given 2 weeks to check out and discuss what is posted!
