This week's free board review question...
A 58-year-old man presents with chest pain consistent with an acute coronary syndrome. Electrocardiography (ECG) is obtained (see Figure).
Figure. Reproduced from Life in the Fastlane. Left main occlusion.
You think that the patient is a candidate for coronary artery bypass surgery instead of an emergent percutaneous coronary intervention because of the findings you observe on ECG.
What finding on ECG is driving you to conclude this?
diffuse PR elevation
ST elevation in aVR with diffuse horizontal ST depression
lack of ST depression in lead V1
lack of ST elevation in lead V1 and narrow QRS complex
